TIPS: You want your taillights to be as bright as possible. This canister will reflect light off the back of the canister and out the lens better than a dark metal canister. To make it even more reflective, line the back with aluminum foil tape. ***Because this is a reproduction part and not the original light can,(which is now obsolete and unavailable), slight enlarging of the opening in your trailer may be required when installing.
WIRING NOTE: This taillight has one 1157 bulb. An 1157 bulb is an indexed two-filament bulb. That means that it has two filaments of different sizes. The brighter filament is wired to your turn signal and your brake. The dimmer filament is wired to the running lights. There is no ground wire. The bulb is grounded to your trailer body through the canister.
