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 smaller #67 bulb. A #1157 bulb is an indexed two-filament bulb. That means that it has two filaments of different sizes. A #67 bulb is a one-filament bulb. In most cases, the smaller #67 bulb is wired to your turn signal. The smaller of the two filaments in the #1157 bulb is for your running lights. The larger filament is normally for your brake lights. 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 zinc plated mild steel.
