Abstract

One or more auxiliary lighting systems are attached to the exterior of a motor vehicle. A control module is located in the engine compartment and connected to the auxiliary lighting system(s) and the battery. A very low power transmitter, located in the cabin of the vehicle, transmits a simple pulse or an encoded signal, depending upon the number of auxiliary lighting systems used. The module includes a receiver and a sensor for detecting the operation of the vehicle'"'"'s original equipment lighting. Logic within the module turns on the auxiliary lighting upon request in accordance with predetermined conditions, such as low beams but not high beams being turned on.

Claims

1. In a lighting control system for a motor vehicle having a battery and driving lights, the improvement comprising:

transmitter means, located in a cabin of said vehicle, for producing a low power radio frequency;

a lamp mounted on an exterior of said vehicle;

a control module, including receiving means, for mounting outside the cabin of the vehicle remote from said lamp, said receiving means responsive to said radio frequency signal for connecting said battery to said lamp and thereby energizing said lamp;

wiring means for interconnecting said lamp and said control module;

said lamp being controlled from within the cabin of said vehicle by operation of said transmitter means without a direct electrical connection between said transmitter means and said control module; and

sensing means responsive to an illumination condition of said driving lights to inhibit energization of said lamp.

2. The lighting control system as set forth in claim 1 wherein said control module is mounted within an engine compartment of said vehicle.

3. The lighting control system as set forth in claim 1 wherein said system includes a plurality of lamps, said transmitter produces a tone encoded signal, and in which said control module comprises:

decoding means, coupled to said receiving means, for detecting the presence of a predetermined code; and

logic means for selectively operating one or more of said lamps in accordance with said predetermined code.

4. The lighting control system as set forth in claim 1 wherein said control module includes recessed sockets and said wiring means comprises plugs for fitting into said sockets.

5. The lighting control system as set forth in claim 4 wherein said plugs and sockets are shaped to prevent rotation thereof when engaged.

6. The lighting control system as set forth in claim 1 wherein said transmitter produces an encoded signal and said control means includes

a plurality of switch means and

decoding means connected to said plurality of switch means for selectively controlling more than one lamp.
