The Grote LED Lamp Series includes a 6” oval and 4” round Stop/Tail/Turn (S/T/T) lamps, each equipped with an LED built-in back-up lamp. Combining S/S/T and back-up functions, these lamps allow the elimination of two holes and two lamps at the rear of straight, vocational and specialized vehicles, and eliminate the need for separate back-up lamps on HD power modules. This design eliminates potential leaks in vehicles, improves structural integrity and corrosion resistance, and leaves more room for other lamps and controls, as well as lift gates, emergency flashers, and grab rails. Grote designs fit existing 6” oval and 4” round grommets and flanges.
