Abstract
A portable, radio controlled light bar magnetically affixable to a trailer or towed vehicle that receives signals from a transmitter magnetically affixable to the tow vehicle and electrically connected to its braking, turning and tail lighting systems. The light bar includes a pair of turn signals and a pair of tail/braking lights, each of which has a parabolic lens for magnifying the light emitted thereby requiring less light to provide sufficient brightness or lux. The transmitter includes a four prong receptacle that is readily connectable to a standard wiring harness on the tow vehicle. The radio frequency is adjustable so each unit has a unique radio frequency. The transmitter operates off of the voltage supplied by the tow vehicle while the light bar operates off of a rechargeable battery and the radio frequency signal received. A recharger is supplied on the light bar.
