USDM vehicles were not equipped with a rear fog light from the factory. They only have a plastic cap covering up the center of the rear bumper. No lamp, mounting bracket, mounting hardware, or wiring.
This GCS lamp includes the required parts to mount it to your USDM vehicle.
Crazy these don’t come standard with USDM models. Really completes the look in addition to adding an additional functional safety factor. Pretty straightforward install. Would really recommend the quick connect wires as well to make install easier.
