Super bright LED panel installs behind existing lens for ALL 1967-72 Fleetside Trucks, Blazers and Suburbans. Unlike the original assembly which uses the lower portion of the lens as a reflector, BROTHERS LED Panel will illuminate the entire lens from top to bottom. The Dual Function assembly serves as a taillight & bright stop/turn signal. Easy plug-n-play connection into your standard 1157 socket requires ZERO modification to vehicle. Molded to fit original housing with foam padding and tabs to secure lens in place. Complete vehicle LED conversion will require addition of an electronic flasher due to small voltage draw. Sold as each.
