This is a stainless steel reproduction of the backing plate, bulb socket bracket, bulb socket, wire leads and bulbs for the Bargman Trail-Lite No.99 taillight lens. It is everything you need except the lens, gasket and 3 lens mounting screws. It fits our Trail-Lite No.99 lens perfectly and has a diameter of 6-1/4". There are three mounting holes spaced like a triangle with distances measuring 3-3/16", 3-23/32", and 3-7/16".
If you need the complete assembly, we now offer this backing plate with a lens, gasket and screws for a discounted price!
WIRING NOTE: This taillight has one 1157 bulb and one 67 bulb. An 1157 bulb is an indexed two-filament bulb. That means that it has two filaments of different sizes. An 67 bulb is a one-filament bulb. There is no ground wire on either bulb. The bulb is grounded to your trailer body through the socket body and backing plate.
Construction: Backing plate and bulb socket brackets are 24ga 430 bright annealed stainless steel. Threaded screw holes are aluminum. Bulb sockets are mild steel.
