Wireless control for auxiliary lighting

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.
