Automatic low beam lighting ensures that the vehicle driver does not have to consciously switch on the safety mechanism.

The present invention avoids the problem of battery power leakage during ignition when automatic low beam lighting is used since there is no switching on of the lights until the vehicle ignition is complete.

In many embodiments of the invention, the starting device is connected to the vehicle's standard headlights, so that it can be installed on existing as well as new vehicles without the need for extra lights. Many embodiments of the invention contemplated also include a starting device connected to the tail lamps of the vehicle as well as the headlamps.

Features of the invention preferably include that the headlights are also switched off when the engine is switched off to prevent a flat battery, which closes when no power is supplied by the ignition system. This can be achieved by using relays.

In a preferred embodiment, the present invention incorporates a fail-safe mechanism so that if the starter fails for any reason, other operations of the vehicle, including headlight operation, will not be affected, which may be due to This can be accomplished in a number of ways by using blocking diodes or other devices to open relays when power is removed.

In many embodiments, an override switch is provided, perhaps located on the underside of the hood of the vehicle, for the purpose of switching off the lighting system if the driver of the vehicle does not wish to use the invention under certain circumstances. Good morning.

Preferably, the invention comprises two
~3 wires extending from it The method of packaging the invention in this way makes it easy to install the invention in existing vehicles since all that is required is to properly connect the wires. For example, in many embodiments, the wire is
One tree is required to connect to the dip light, one to connect to the high beam light, one for ignition, and one for the tail light.

In many embodiments, the modular unit is filled with a resin that provides an anti-motion unit. The present invention is sufficiently inexpensive that it is contemplated that if something goes wrong with the module unit, the module unit can be discarded and replaced.

The invention contemplates numerous embodiments operating at different voltages. Alternatively, an embodiment may include a device that allows selection of the desired operating voltage. This could be accomplished with the use of potentiometers or other variable and adjustable components.

A convenient place to locate the invention would be under the hood of a vehicle.

It will be appreciated that the present invention can be used with a variety of vehicles such as motorcycles, aircraft, earth movers, cars and trucks.

Aspects of the invention will now be described, by way of example only, with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, there is provided a starting device generally indicated by arrow l, including an ignition device 2, a switch 3, a timer 4 and a warning light 5.

Switching on the igniter 2 activates the switch 3 which starts the timer 4. At the same time, the warning light 5 is switched on to indicate that the starting device I is activated.

The timer 4 can be operated by various devices, for example,
This timer 4 can be an electronic timer, such as a monostable integrated circuit; alternatively, the timer can be mechanical or operated by a bimetallic piece.

The time-out period of timer 4 could be factory set for a predetermined period of time, perhaps between 20 and 60 seconds. Alternatively, timer 4 is adjustable by the vehicle operator.

Once timer 4 times out, relay 6, which is connected through line 15 to the lamp actuator indicated by dotted box 7, is set. A diode 16 is interposed between the timer 4 and the relay 6 to prevent excitation of the lighting system by any other device from feeding back into the ignition system.

Inside the lamp operating section 7 are headlight sections 8 and 9, a high beam line 10 and a low beam line 11, a relay box 12, a dip switch 13, and a high beam warning lamp 14.

The headlights 8 and 9 are equipped with dark lights 8a and 9a and high beam lights 8b and 9b, respectively.

The relay box 12 is equipped with a relay 12a that connects to the dark lights 8a and 9a through the high beam line IO and a relay 12b that connects to the high beam lights 8b and 9b through the low beam line 11.

A dip switch 13 is connected between the high beam line 10 and the low beam line 11.
The switch is the same as used in most vehicles.

Relay 6 is connected to relay 12a by line 15;
Therefore, it is connected to the low beam line 11. relay 6
In the absence of power from the ignition device a12 to the ignition device a12, the relay 6 is closed to isolate the low beam line 11 from the ignition device 2. When timer 4 times out and power is provided from igniter 2 to relay 6, relay 6 is pulled open and current is passed to line 15, relay 12a, low beam line 11 and low beam dim light 8a. and 9a. In this way, the operation of the dark lights 8a and 9a, which are low beam headlamps, is controlled by the dip switch 1.
This does not affect the high beam operation of high beam lamps 8b and 9b, which can normally operate through 3.

When igniter N2 is switched off, relay 6 is de-energized and remains open. Closing relay 6 disconnects dark lights 8a and 9a from the power supply. Therefore, when the vehicle is switched off, the various lights are also switched off.

Tail light 18 is connected to line 15 via line 19. Therefore, when the dark lights 8a and 9a are switched on by closing the relay 6.

The tail light 18 is also switched on. A diode 17 between the tail light 18 and the line 15 connects the tail light 18 to the ignition device 2 if the tail light 18 is energized by any other device.
Make sure there is no hefty food back.

However, in most cases the invention is supplied in modular form and has only one wire or two wires connected to the ignition device 2 and the other wire or two wires connected to the low beam line 11. It is not intended to be.
