Abstract: This invention comprises an auxiliary light apparatus for use in combination with a backup light apparatus of a truck or other vehicle. The auxiliary light apparatus comprises a male or female electrical plug for connection to a mating plug on the original vehicle backup light apparatus; an electrical voltage relay element in the auxiliary plug apparatus; a toggle switch in the auxiliary apparatus and auxiliary lights mounted on the vehicle. The auxiliary lights function simultaneously with the original vehicle backup lights in response to activation of the reverse gear apparatus of the vehicle transmission, with the voltage relay acting to deliver sufficient voltage to activate both the original vehicle backup lights and the auxiliary lights. In another embodiment of the invention, the toggle switch is closed to access directly the vehicle 12 volt source to power the auxiliary lights for use as work lights, even when the vehicle reverse gear is not engaged.
