These were once readily available from every speed shop and every "Hot Rodder" had one. We decided to bring back this bit of nostalgia. Originally there were two sizes. We made the small style because we thought it was a lot cleaner. The quality of the original one was poor, so we improved ours by stamping it from stainless steel, molded a lens, added a license bracket, molded a rubber pad, tossed in some stainless screws and a 12-volt bulb. You’re gonna love it.
