Abstract: A reverse light assembly that is mountable on the rear of the trailer portion of a tractor-trailer or similar vehicle. The reverse light assembly comprises a reverse light housing removably or permanently securable to the rear of a trailer by means of brackets and fasteners, such as screws, or bolts, among others. The reverse light housing includes one or more lights thereon to provide illumination in the rear of the vehicle and illuminates to indicate that the tractor-trailer is in reverse. The reverse light housing may be remotely operated by a control unit inside of the cabin of the vehicle or by a key fob device so that the user can selectively illuminate the lights thereon. Alternatively, the reverse light assembly may be operably connected to the vehicle's electrical system so as to allow the lights to automatically illuminate when the tractor-trailer is shifted into reverse.
