The light is mounted underneath an outer edge of the trailer of the tractor-trailer so that they would be extendable laterally away from the edge of the trailer so that the light portion of the present invention would extend far enough outwardly to travel beyond the outer edge of the trailer so that the beam of light emanating therefrom would illuminate the area behind the rear of the trailer. An air cylinder operated by an electrical actuator controlled by the driver and/or the transmission of the truck would actuate the light portion so that the light portion would extends from an enclosure and beyond the edge of the trailer of the truck-trailer when the transmission is placed in reverse and then the light portion would be retracted back into the enclosure by an electrical actuator when the transmission is taken out of reverse.
