Abstract
A vehicle light system has light modules 10 (fig 3) mounted along opposite sides of the vehicle, and rear light modules 12. The side modules display white and amber whereas the rear modules display red and white. A control unit 40 powered by the vehicle has a speed input from a GPS 48 or tachograph, causes the amber lights to be turned on below a predetermined speed (e.g. 18mph) and turned off at higher speeds. A directional input from left and right indicator circuits of the vehicle enables the amber lights to flash on a corresponding side of vehicle when the vehicle is turning. A reversing input from a reversing light circuit of the vehicle turns the white lights on and inhibits the amber lights. The rear red lights are on when the vehicle's side lights are on. If both directional inputs are activated, the amber lights are turned off. The control unit 40 is in a housing (figs 6-8) with connectors for chains of light modules.

- 5 DETAILED DESCRIPTION OF THE DRAWINGS
Referring firstly to Fig.s 1 and 2, a vehicle 1 has a cab 2 with an engine, and a rear transport portion 4. The vehicle may be a rigid or an articulated vehicle wherein the rear portion 4 is a separate trailer which can be detached from the cab 2. In this embodiment, the trailer 4 has a chassis 5 provided with wheels 6, which supports a tipping body 7 in which various loads may be carried.
The vehicle 1 is provided with a vehicle warning light system which may be installed entirely within the trailer 4. The warning light system includes side light modules 10 which are installed along both sides of the vehicle. The side light modules are conveniently fitted to the trailer chassis 5 above the level of the wheels 6 but below the trailer body 7. The modules 10 are spaced along the length of the trailer, as shown. As can be seen in Fig. 2, additional rear light modules 12 can be installed at the rear of the vehicle, mounted to suit customer requirements. In the case of tipping vehicles such as this the rear light modules 12 may be installed at spaced positions across the top of the trailer body as shown, but not necessarily so. They could also be installed on the chassis for example.
One of the light modules 10 and 12 is shown in Fig.s 3 and 4. Each light module comprises an elongate body 20 mounted between a pair of end fittings 22. The body 20 comprises upper
- 6 and lower LED light strips 23 and 24. The upper light strip 23 provides a white light whereas the lower strip 24 provides an amber light in the case of the side light modules 10 or a red light in the case of the rear light modules 12. The end fittings 22 are substantially identical, each having upper and lower mounting flanges 26 and a 4-way connector 28. The two connectors both provide identical electrical connections, as follows:
28.1 Red/amber light supply
28.2 Red/amber earth
28.3 White light earth
28.4 White light supply
The connectors 28 are wired through so that power input can be from either end, and in addition, the light modules can be connected in a chain with the output from one light module providing the power input to the next module in the chain. Three chains of modules are wired, one at the left side of the vehicle, one at the right side, and a third at the rear (when provided). In order to direct the light downwards the light modules may be secured to the vehicle using stainless steel angled mounting brackets 30 as shown in Fig. 4, or using wedge-shaped spacers for example.
Referring to Fig. 5, all the light chains 10 and 12 are connected to an electronic control unit 40 which may be mounted in any convenient position on the vehicle. The electronic control unit 40 incorporates a microcontroller 47 and an optional in-build GPS receiver 48. As an alternative to a GPS receiver the control unit
- 7 may be connected to the vehicle tachograph. The microcontroller controls all the functions of the light system, as explained below. The vehicle's speed is calculated by the GPS receiver or taken from the tachograph and sent to the microcontroller. The electronic control unit also incorporates a dedicated flasher module 49. Input connections are taken to the microcontroller from the vehicles left and right turn indicator circuits and from the reversing light circuit. When the rear light modules 12 are used the red lights are connected to the vehicle's side light circuit. The warning light system is powered from the vehicles ignition circuit.
From zero speed up to a predetermined speed, typically less than 18 mph but not necessarily, the amber lights in the side light modules 10 are permanently on at both sided of the vehicle. Once the predetermined speed is exceeded the amber lights switch off, but they automatically come on again if the vehicle speed drops below the predetermined level. When the turn indicator circuit for either side of the vehicle is triggered, indicating a left or right turn, the amber lights on the corresponding side of the vehicle flash to warn other road users of the manoeuvre. The amber lights are operated by the flasher unit 49 of the electronic control unit so that they flash in a different pattern to the vehicle's turn indicator lights, which is considered better for attracting attention. The amber lights on the opposite side of the vehicle stay switched off, again to highlight the manoeuvre.
If the vehicle's hazard lights are used both of the vehicles turn indicator circuits are activated simultaneously. When this occurs
- 8 the control unit 40 does not illuminate the amber lights on either side of the vehicle. This is for two reasons: firstly it can cause confusion when loading or unloading, and secondly, in certain European countries the use of hazard lights in prohibited on moving vehicles on the highway.
When the vehicle performs a reversing manoeuvre the amber lights do not function, and the white lights are switched on down both sides and at the rear of the vehicle. This surrounds the entire rear and sides of the vehicle with white light which gives the driver a clear virtual daylight view during this potentially dangerous manoeuvre.
The red lights on the rear of the vehicle are illuminated whenever the vehicle's side lights are on.
Referring to Fig.s 6 to 8, the control unit 40 has an impact-resistant waterproof plastic housing 41 provided with integral mounting brackets 42 and ten integral Super Seal connectors 45. The connectors 45 provide two input connectors and nine output output connectors for driving the chains of light modules 10 and 12. The connections to the various connectors 45 are as follows:

The connection to the vehicles ignition circuit is used to power the warning light system. The direct battery connection is fed straight through so that it is available to power any external systems when the ignition is off. The two AUX output connectors provide ignition circuit and battery outputs so that they are available if required.
The vehicle light system is easy to install and provides useful additional warning features for drivers and others in the vicinity of the vehicle.
Whilst the above description places emphasis on the areas which are believed to be new and addresses specific problems which have been identified, it is intended that the features disclosed herein may be used in any combination which is capable of providing a new and useful advance in the art.
