There is a low luminosity warning light at the keyboard center.

Description

<Desc / Clms Page number 1>

The present invention arises from the technical field of safety during travel and transport in that it relates to an optical device allowing people who have observed the presence of a traffic danger, to report it immediately and silently to d 'other persons concerned, before they are unexpectedly and directly exposed to this danger.

avant tout la sécurité en matière de circulation terrestre et plus particulièrement de circulation routière. This invention relates to the safety of all modes of travel and transportation, but is intended

above all safety in terms of land traffic and more particularly road traffic.

In this matter, this device allows a pilot or passenger who has observed the presence of a danger on the traffic lanes which he uses or which are very close to it, to immediately give the alert to users who come across him, follow him. or double it, indicating to them, at the same time as their presence, the nature and location of the risks incurred.

Regarding road traffic, it is traditionally the responsibility of those responsible for its organization, its surveillance and its security, to inform users of the dangers they run on the roads they take, by using either signs or lights. fixed signaling, either of luminous panels animated by information, or by the implementation of specialized personnel equipped with mobile means appropriate to the dangerous situations noticed unexpectedly.

In all cases a delay is necessary between the fact generating a danger, its observation by a person, the information of qualified traffic or security officials, and the taking by them, even from a distance, protective measures or, a fortiori, movement and implementation on the premises of appropriate means and, in particular of very effective means of signaling the danger existing to users traveling in both directions of traffic; For this reason, the period of warning users on the road or motorway section, which presents a danger, is more than enough so that, in general, very many accidents cannot be avoided and, in particularly on motorways, chain pileup.

On the other hand, this period of warning users is considerably, or even totally reduced in the vast majority of cases, if appropriate equipment is made available to users, so that they can alert each other, at night as well as at night. day, whatever their language, age and model of their vehicle, or even whatever the traffic and driving habits, such as right-hand driving or left-hand driving.

The solution of the problem can only be brought about by using one of the two human senses: hearing or sight.

 - The direct transmission of sound signals between vehicles must be excluded, since it is not possible to either choose sound horns powerful enough to alert users of a freeway traveling in the opposite direction, or to signal a danger in urban areas, especially at night, while audible warning devices are preferably prohibited.

 - The wireless transmission of sound (radio) or data would be satisfactory as regards its range between users and without creating noise pollution outside vehicles, but would require on the one hand, the use of specific equipment, with transmitters and receivers using well-defined frequencies, authorized on all territories and, on the other hand, the use of a common language, if possible for all users of the planet, with the constraint for each of them a permanent and attentive watch on frequencies preferably reserved for this single security function.

 - On the other hand, optical transmission provides a particularly advantageous solution both in terms of the range and the absence of nuisance; although the field of perception of a light source is limited to its direct view, even a brief vision of a very characterized light beam is sufficient to be recorded by any user passing through this beam, even if this crossing is made quickly and without special attention previously awakened.

The current lighting and signaling equipment of vehicles being intended for the only uses for which they were designed, authorized or made compulsory, it is advisable not to take any risk, either to limit their effectiveness (headlights or codes, fog lights or long range), or to make their meaning less obvious (position lights, change of direction, braking or reversing lights, special lights); any device for the emission of warning lights must therefore be different and complementary to the optical devices already existing and moreover fulfilling regulated functions.

véhicules déjà en circulation. In terms of road safety, any technical solution to the problem as posed above requires, in order to be able to be implemented effectively, that the road user acquires essential ease, on the one hand to quickly choose the warning light to be emitted according to the dangerous situation encountered and, on the other hand, to understand, from its perception, the meaning of the warning light emitted by another user; such a technical solution also requires that the equipment be designed so as to be easily adaptable to the entire fleet and, in particular, to all

vehicles already in circulation.

The present invention provides a global solution to this major road safety problem and satisfies all the aforementioned constraints which are associated with it: - adaptability to any new or old vehicle, whether intended for right-hand driving or left-hand driving , - common language usable on a planetary level, - simplicity of use, as well for the emission of the warning lights as for their comprehension upon reception, - no need for reception equipment, one transmitter per vehicle is necessary and sufficient.

So that the road safety problem posed can be technically resolved with an optical device, it is essential to have, in the event of danger, a conventional code of light signals.

The code set out below is such that the characteristic signals, called warning lights, make it possible to specify both the presence and the nature of the danger, as well as its location on the roadway.

Depending on the nature of the most common road hazards, it is possible to distinguish two categories of dangerous situations: a / -Dangerous situations due to a very slippery surface: * patches of frost, ice, hail, snow, ice cream,...

* puddles of oil, gas oil, hydrocarbons or other syrupy or slippery products, ...

* sheets of mud, wet leaves, "rolling" gravel, ...

* pools of water deep enough to cause the phenomenon of aquaplaning, b / -Dangerous situations due to an obstacle on all or part of the roadway: * pileup of vehicles, * wandering on the roadway of a child or a individual, domestic or wild animal, ...

 * presence of a crowd, a group of children or cyclists, occupying part of the roadway, * person, cycle, motorbike or overturned load on the roadway, ...

 * bulky fixed or mobile object on the road, ...

 * vehicle not signaled during loading or unloading on the road, ...

 * broken or damaged vehicle clogging the roadway, * sagging or falling on the roadway of electric or telephone lines, or other cables, ...

 * falling rocks, rocks, branches, trees, poles, pylons, ...

 * landslide, mudslide, avalanche or snowdrift, road flooding, ...

 * traffic jam, dam, closed level crossing, poorly or unreported work, ...

 * deep ruts, subsidence of the road, ...

 * sudden and thick sheet of fog, smoke, dust, sand, ...

 * vehicle driving very dangerously: in the opposite direction of traffic, zigzagging on the road, ...

 * unlit vehicle traveling or parking on the road, at night or in fog, ...

- Soit sur la partie de chaussée correspondant au sens de circulation de l'usager "émetteur" du signal, - Soit sur les parties de chaussée correspondant à la fois aux deux sens de circulation. Furthermore, depending on the location of the danger on the road, it is possible to distinguish three categories of dangerous situations from those which may arise for the user "signal transmitter", who recognizes this danger and signals it to other "receiver" users of the signal, this danger can only be located: - Either on the part of the carriageway corresponding to the opposite direction to the direction of traffic of the user "transmitter" of the signal,

- Either on the part of the carriageway corresponding to the direction of traffic of the user "transmitting" the signal, - Or on the parts of the carriageway corresponding to both directions of traffic.

<Desc / Clms Page number 3>

 By taking into account both the nature and the location of the danger, four categories of dangerous situations must be taken into account: Dangerous situation no 1 = very slippery road, (the risk of slipping can concern all users who meet or follow the user "transmitter" of the signal) If the risk of slippage is observed on part of the roadway, it should indeed, as a precaution, consider that the entire roadway may present the same risk in the area considered; the user who has observed such a risk in his direction of travel is moreover not able to validly assess the total absence of this risk on the opposite direction lanes.

(l'obstacle se situe sur les voies qu'empruntent les usagers qui suivent ou doublent l'usager "émetteur" du signal) Situation dangereuse no 4 = obstacle dangereux sur la chaussée dans les deux sens de circulation. Dangerous situation no 2 = dangerous obstacle on the road in the opposite direction to the direction of traffic of the user "transmitter" of the signal, (the obstacle is located on the tracks used by users who meet the user "transmitter" of the signal) Dangerous situation no 3 = dangerous obstacle on the roadway in the direction of traffic of the user "transmitter" of the signal,

(the obstacle is located on the lanes used by users following or doubling the user "transmitting" the signal) Dangerous situation no 4 = dangerous obstacle on the road in both directions of traffic.

(the obstacle relates to all users perceiving the warning light emitted by the user "transmitter" of the signal) The device according to the invention allows the user having observed on the roadway the existence of a danger, to report it immediately to the other users concerned, before they run the risk of being the victim of an accident.

The device according to the invention makes it possible to emit one or the other of four different warning lights, each of these four characteristic warning lights corresponding to one of the four danger situations described above, this characterization being both original enough not to be confused with signs having other meanings and simple enough to be easy to present, teach, understand and memorize by all users.

The present invention relates to a disoositifooticrue intended for the emission either of a single, or of two, or of three light beams generated from one, or from two, or from three ranges of stationary monochrome light appearing in two forms. and two very different colors, which allows the user "transmitter" to have the choice between one or the other of four combinations of the three light beams, each of these four combinations being associated with one of the four dangerous situations as previously defined.

This optical device is composed of emission means, control means, connection elements and, in the absence of integration into the vehicle body, of fixing elements thereto.

 - The emission means (Fig. 1, Fig. 2, Fig. 3 and Fig. 4) are characterized by a longitudinal light emission ramp consisting of three ranges of stationary monochrome light defined by shapes, colors, a light intensity, positioning and orientation relative to the direction of movement of the vehicle.

The three light areas are characterized in that two illuminating areas (16) (17), identical in intensity, shape and color, located symmetrically on either side of a central illuminating area (15) whose shape and the color are very different from the shape and the color of the two lateral areas (16) (17), this central illuminating area (15) being itself located in the middle of the emission ramp intended to be adapted, by integration or, failing that, by fixing, to the vehicle body.

The shape of the central light area (3) is punctual and of small dimensions, a few centimeters, while the shapes of the two lateral illuminating areas (4) (5) are identical and symmetrical with respect to the central area (3 ), and correspond to an elongated shape whose length (a a'or b'b) is at least two to three times greater than that (a'b ') of the central illuminating surface (3).

<Desc / Clms Page number 4>

 To be sufficiently clear when viewed at a distance of fifty meters, day and night, the three light ranges, at the origin of the three light beams, are separated from each other by two spaces limited (6) non-luminous, located between the central illuminating surface (3) and each of the two lateral illuminating surfaces (4) (5). The dimensions of these two non-luminous spaces between ranges of light depend in particular on the level of intensity used to adjust the brightness of the light sources, which must remain non-dazzling, and on the dimensions of these ranges of light.

Depending on the size of the vehicle, the dimensions of the ramp may indeed be greater or less, as long as the proportions and the symmetry of the two lateral illuminating surfaces (4) (5) relative to the central illuminating surface (3) are respected.

The monochrome of the light areas at the origin of the monochrome light beams is obtained: - with one or more white light sources such as incandescent filament lamps or luminescent tubes, positioned either (Fig. 1b) under screens (9) (10 ) and (11) in translucent and colored material, either (Fig. 1 a) in front of reflectors in reflective and colored material, - or with one or more colored light sources, such as color and high-brightness light-emitting diodes or discharge tubes, positioned under covers of colorless, translucent or transparent material, - or with one or more light sources combining the above characteristics.

The two lateral light areas (16) (17) are of the same color opposite or very contrasting with that of the central light area (15) which remains the characteristic benchmark of the emission device (FIG. 1d) and, for this, is systematically lit in one or other of the four possible combinations of lighting of the three ranges; the two reference colors for this optical warning device are purple for the central light source and yellow, opposite color for purple, for the two lateral light sources.

The light intensity, which results from the power installed in each of the three illuminating surfaces and from the light transmission coefficient of the translucent protective cover of these areas, is constant for each of them, in order to avoid any confusion between these lights. 'stationary alert and signaling lights or other special flashing, pulsed or rotating lights, already regulated. In addition, to respect the symmetry of appearance of the two lateral areas (16) (17), their light intensities are identical to each other and, moreover, less than or equal to the light intensity of the light source corresponding to the area central light (15).

The position of the light emission device on the vehicle (Fig. 9) and (Fig. 10) is such that the warning light emission ramp is integrated (70) (80) or fixed (90) (100 ) horizontally and as high as possible to the bodywork, in order to optimize its visibility for other users, in particular for users who meet the vehicle emitting the warning light on motorway lanes, very often separated by low walls or central rails , as well as by curtains of different types: decorative hedges, anti-glare palisades, etc. This adaptation of the emission device to the bodywork is done in such a way that the central illuminating surface (71) of the light ramp (70) is located in the median longitudinal plane and that the two lateral illuminating surfaces of the light ramp are located in the same horizontal transverse plane, perpendicular to the aforementioned median longitudinal plane.

Depending on the orientation of the light emission ramp on the vehicle (Fig. 12), the warning lights emitted are visible, without being dazzling for other users, either from the front of the vehicle, front model (125) , either from the rear of the vehicle, rear model (126), or from both the front and rear of the latter, dual-orientation model, front-rear (128). Depending on the type of vehicle, several locations are possible for a front model (90) and, in particular (Fig. 4c), coupled with one for a light emission ramp: on the one hand inside the bodywork, either behind the interior central rear-view mirror windshield (21) or behind the rear window (106) for a rear model (100) and, in particular (Fig. 3), coupled with a third brake light (19) or, d on the other hand, in the absence of integration into the body, outside of the latter for a light ramp produced in the form of an accessory, such as a rear boot spoiler incorporating a rear emission device for warning lights or (Fig. 12) an aerodynamic roof fin (128) incorporating a device (Fig. 2) for front-rear emission of warning lights.

The reference location for this signaling device is that which makes it possible to place the central light beam (71) in the median longitudinal plane of the vehicle and, for road vehicles, at a minimum height of 1.50 m, this distance from the ground being greater in the case of heavy vehicles.

<Desc / Clms Page number 5>

A limitation of the solid angle of projection of the warning lights is necessary, depending on the model of ramp and according to its positioning and its orientation on the vehicle, in particular when the warning lights are oriented in front of the vehicle, these elements for guiding the light beams are intended to prevent parasitic reflections, in particular on the parts of the bodywork located at the front of the vehicle, that may be the cause, in particular at night, of an optical nuisance for the driver and for its passengers or, for other users, a misinterpretation of the warning lights perceived; the light beams are guided with an increase in the depth (ae) of the compartments (3) (4) (5) of the housing of the light emission ramp (Fig. 1 a) and, if necessary, by an adaptation very precise from the shape of the walls of this box to the shape of the surface of the bodywork and in particular (Fig. 10a), to the curvature of the windshield (96) for a front emission ramp (90) intended to be positioned behind this windshield, or at the curvature of the rear window (106) for a rear emission ramp (100) intended to be positioned behind this window.

 - The control means of the above-mentioned transmission device are characterized by an ergonomic switch (Fig. 6), with five control positions, including the stop position in the center of the device, and with four indicator lights corresponding to a watch and three warning lights; any configuration of lighting of one, two or three indicator lights on the keyboard of the switch corresponds to a configuration of similar lighting of one, two or three ranges of light on the light emission ramp, and any lighting of a range of light on the ramp results in the emission of the corresponding light beam.

Four different combinations are thus possible with the three light beams having all the physical characteristics described above, each of these four combinations of beams corresponding to the emission of one of the four warning lights.

On the switch shown in Fig. 6, the five control positions B, C, G, D, H, are indicated in FIG. 6a and the location of the five corresponding keys (39) (40) (41) (42) (43) in FIG. 6b, three keys (40) (41) (42) serving as an indicator light (47) (48) (49) for issuing a warning light and one of these keys, the central key (47), serving also, by its luminous perimeter, standby indicator (38).

As soon as the engine ignition is switched on, the standby warning light (38) of the switch comes on while the control device is in the stop position, which, day and night, immediately makes it possible to locate the location of the switch in the cockpit, as well as the arrangement of the keys on its keyboard (Fig. 2a '), this standby indicator (38) also remaining lit when the switch is in one or other of the five positions of command B, C, G, D, H.

Independently of this standby indicator (38), which remains on as long as the engine contact is established, this switch allows, at the user's choice: - either, with the low key B (Fig. 6c), to switch on the central light area (15) of the transmission ramp (Fig. 1) as well as (Fig. 6d) the central indicator light (47) on the control panel of the switch (37), - either, with the left key G ( Fig. 6e), to switch on the central, (15) and left lateral (16) lights, of the transmission ramp (Fig. 1), as well as (Fig. 6f) the central, (47) indicator lights and left side (48), of the control keypad (37), - either, with the right button D (Fig. 6g), to switch on the light, central (9) and right side (11) areas of the ramp emission of warning lights, as well as (Fig. 6h) the indicator lights, central (47) and right side (49), of the keyboard (37), - either, with the high key H (Fig. 6j) , to switch on the three light zones, central (3), left side (4) and right side (5), of the warning light emission ramp (Fig. 1), as well as (Fig. 6k) the three indicator lights, central (47), left side (48) and right side (49), of the switch control keyboard (37).

 - or, with the central key C (Fig. 6m), at the same time extinguish any warning light on the transmission ramp (Fig. 1) and (Fig. 6n) any indicator light on the keyboard of the switch (37), which is done automatically, with the exception of the standby indicator (38), after a predetermined time when the control device is equipped with a timer.

Each of the four control positions B, G, D and corresponds to the emission of a particular warning light, which is reflected, on the one hand on the emission ramp (Fig. 1d), by the lighting of one or more light zones (15) (16) (17) and, on the other hand on the keyboard of the switch (Fig. 6k), by lighting of one or more indicator lights (47) (48) (49) whose colors and positions on the switch keypad (Fig. 6k) are similar to the colors and positions of the light areas (15) (16) (17) of the emission ramp (Fig. 1d). These indicator lights (47) (48) (49) light up in total synchronism with the light sources corresponding respectively to the three light areas (15) (16) (17) located (Fig. 1d) on the emission ramp. warning lights.

<Desc / Clms Page number 6>

Whatever the model of the warning light control device, switch with five-way joystick, switch with keyboard with five, four or three touch, press or rocker keys, the four indicator lights (38) (47 ) (48) (49) allow the user, night and day: - to locate, at the vehicle driving position, the exact location of the buttons on the optical horn; - ensure, by the standby indicator, that the control device is electrically supplied and ready to operate; - to make a choice on the switch between five possible positions making it possible to obtain either the emission of one or the other of the four warning lights, or the stopping of any emission of warning light, - visually and quickly ensure that the warning light emitted corresponds to the situation encountered; - to ensure, if necessary, the absence of any emission of warning lights.

This ergonomic switch with five control positions and four indicator lights corresponds, in particular, either to a switch with five-way lever (Fig. 5a to 5n) or to a switch with five-button keypad (Fig. 6a to 6n ), or to a switch with a keyboard reduced to four keys (Fig. 7a to 6n) or to three keys (Fig. 8a to 8n).

For the key switch models, the surface of the central key is preferably marked by a concavity and a roughness allowing, with the single touch, to confirm its precise situation under the fingers of the user.

The luminous part of the standby indicator can be, in particular, either the entire lever (26), its base or its other end, or the perimeter contour (22) of the central button.

Are incorporated in the housing of such a switch (Fig. 6b), a timer (44) with preset duration, associated with a buzzer (45) intended to remind the user, in an audible although discreet manner, that a warning light emission is in progress on his vehicle, as well as a dimmer (46) of light intensity allowing the user to increase the visibility of his warning lights, if necessary in fog, dust or smoke, or under snow, hail or rain.

The mounting of these three elements (44) (45) (46) for controlling the lights is such that the timer (44), automatically started, for a cycle of predetermined duration, by the sole use on the switch of one of the warning light emission commands, causes the buzzer (45) to operate immediately, and, in the same way, the end of the cycle programmed on the timer (44) causes the buzzer (45) to stop at the same time that the extinction of any warning light and this (Fig. 12), whether the emission device consists of a single front ramp (130) or two light emission ramps, front ramp (125) and rear ramp (126) or a front-rear ramp (128).

Whatever the position on the vehicle (Fig. 9 and 10) of the warning light emission ramp, on an exterior face of the bodywork, either at the front (70) or at the rear ( 80), or on an interior face of the bodywork, either at the front (95) or at the rear (105) of the vehicle, it is necessary to be able, if necessary, to access the sources of electric light (7) , especially for changing a lamp.

To this end, the housing of the light emission ramp (Fig. 1a) comprises movable wall elements allowing access to the interior of the housing, either by its front face (1), in particular when the device for emission is integrated into the bodywork or fixed to it and, therefore, not accessible from the rear, either by its dorsal side (2), especially when the emission device is placed inside the bodywork , for example by fixing behind the windshield (95) or behind the rear window (105), or (Fig. 4c) by integration in an accessory also serving as a central mirror (21).

Whether the warning light emission control device is wired, radioelectric or optical, similar accesses are also provided for its maintenance.

 The integration into the vehicle body, or into one of its accessories, of elements constituting the emission devices can, for example, be carried out: - for a front emission ramp (70), either in a rear view mirror central or in the front sun visor support elements, either at the front edge (75) of the roof, or in the front bar of a gallery or the front edge of an aerodynamic roof fin, or in the front apron d '' a motorcycle, - for a rear emission ramp (80), either at the rear edge (85) of the roof, or in the rear bar of a gallery or in the rear edge of an aerodynamic roof fin, or level of a rear window cap, a door or a rear boot spoiler, either in any rear truck door or bulkhead or trailer, - for a front-rear transmission ramp, in an aerodynamic roof spoiler or, for sports or coach vehicles erie low, in an aerodynamic rear boot spoiler.

<Desc / Clms Page number 7>

Concerning the elements constituting the command and control devices such as switch (Fig. 5) with control lever (26) or switch (Fig. 6b) with keyboard (37) with five keys (39) (40) (41) (42) (43), timer T (44), buzzer S (45) and dimmer V (46) of light intensity, they can be integrated, for example, at the dashboard, the center console, the steering wheel or control accessories mounted on the steering column.

The integration of all or part of the optical warning device in an accessory such (Fig. 3) that an interior central rear-view mirror placed behind the top of the windshield allows, at the same time, a good positioning of the emission device in the median plane of the vehicle and a good positioning of the control device within easy reach of the pilot; such a variant with assembly of the transmission and control devices is optimized (Fig. 4) with a keyboard reduced to three horizontal keys (28) (29) (30) and, in addition to the standby indicator, with three indicator lights ( 23) (24) (25) whose light sources are the same as those (7) of the warning light emission ramp, a window with a colored screen being open in the lower part of the back wall of the housing of each of the three compartments (3) (4) (5) of the emission ramp, any lighting of a range of light in one compartment of the ramp automatically causing the corresponding indicator on the switch side to light up.

With regard to the model of optical warning device acting as an interior central mirror, the plane of the front face (1) of the housing, corresponding to the emission ramp before the warning lights, makes an angle with the plane of the dorsal face (2) of the box corresponding to the support of the mirror (21) of the mirror; this angle is sufficient for the plane of the front face of the ramp to remain substantially parallel to the plane of the windscreen when the mirror is adjusted by the pilot to serve as his rear-view mirror.

All the models of optical warning device comprise (Fig. 11) connection elements (111) between source (110) of electrical energy, control device (114) and control devices (115) (116) (117) and transmission (112), even if the optical horn integrates, in a single device, the power source and the control and emission devices.

In the absence of integration into the vehicle body of the various elements constituting the emission, control and connection devices of the optical horn, fixing elements (8), in particular by adhesion, screwing or snap-fastening, are located on the longitudinal housing of the ramp (Fig. 1,2 and 3) and on the housing (37) of the switch, and their locations are not limited to the ends of the housings and depend on the nature of the materials on the surface of which the equipment subject of the invention is suitable.

- Figures 8a to 8n illustrate a device for controlling the emission of warning lights with a keyboard reduced to three keys and four indicator lights, - Figures 9a to 9e show both the configuration of the lighting of the warning lights of the control and configuration of lighting of the light beams of the forward light emission device and of the rear light emission device of a vehicle, - Figures 10a to 10e represent both the configuration of the ignition of the control device indicators and the configuration of the lighting of the light beams of the warning light emission devices on the one hand forward, adapted behind the windshield, possibly with the function of central rear view mirror, and on the other hand towards the rear, adapted behind the rear window of the vehicle, - Figures 11 a and 11 b show very schematic diagrams of assembly of the component elements two models of optical warning device, - Figure 12 shows a block diagram of the implementation on the road of three models of optical warning device, during a first dangerous situation signaled by the warning light No. 1, corresponding to the risk of skidding due to a slippery road, - Figure 13 shows a block diagram of the implementation on the road of three models of optical warning device, in a second dangerous situation corresponding to the risk of collision due to an obstacle located on the part of the road corresponding to the reverse traffic direction to that of the vehicle X emitting the warning light no2, - Figure 14 shows a block diagram of the implementation on the road of three models of optical warning device, during a third dangerous situation corresponding to the risk of collision due to an obstacle located on the part of the carriageway concerning the direction of movement of the vehicle X emitting the warning light no3, - Figure 15 shows a block diagram of implementation on the road of three models of optical warning device, during a fourth dangerous situation signaled by the warning light no4 corresponding to the risk of collision due to an obstacle located on the entire roadway and therefore concerning both directions of traffic .

In all the figures illustrating the components of a warning light emission device, the concept of left and right follows the same uses as those which are usually used to locate the components of a vehicle such as front wheels and rear wheels or front lights and rear lights.

Thus the left beam of a front emission device is on the left side of the vehicle and is located in relation to the driver of the vehicle, to the left of the central beam, just as the control button for this left beam is located to the left of the center key on the switch keyboard.

Similarly, the left beam of a rear emission device is also on the left side of the vehicle and is located to the left of the central beam of the rear emission ramp seen by an observer following the signaling vehicle.

In these cases of front emission and rear emission of left side beams, the warning lights emitted mean that the danger is located to the left of the driver of the transmitting vehicle and to the left of the users following him, that is to say on the lane (s) located to the left of the middle of the roadway, therefore in the opposite direction to their direction of traffic: they may therefore not be directly threatened by the danger but, informed of it, it is their responsibility, however, to on the one hand, to be vigilant because a situation which is dangerous at a given time in one direction of traffic can very quickly spread on traffic lanes in the other direction, in particular on roadways without effective central separation of lanes and, on the other hand, if they are equipped with an optical warning device, to emit the same warning light as that which they have received, this signal being first intended for the users who follow them then, after acknowledgment of the real presence of the danger, in the us agers who meet them and who are directly concerned.

croisant le véhicule émetteur : cet observateur voit en effet à droite du faisceau central le faisceau latéral émis ce qui, pour lui, signifie effectivement que le danger se situe à droite, ou plus exactement à droite du milieu de la chaussée, c'est à dire sur la ou les voies ouvertes dans le sens où il circule : il est donc très directement menacé par ce danger, ainsi que les autres usagers circulant dans le même sens que lui. The vision of a warning light corresponding to the emission of the central beam and the left lateral beam, as in the previous example, is completely reversed when this vision is that of an observer

crossing the transmitting vehicle: this observer sees indeed on the right of the central beam the emitted lateral beam which, for him, effectively means that the danger is located on the right, or more exactly on the right of the middle of the road, it is at say on the open lane (s) in the direction in which it is traveling: it is therefore very directly threatened by this danger, as well as other users traveling in the same direction as it.
