GCS CS Style F1 Rear Fog Light - WRX / STI 2015+
REAR FOG LIGHT / 4TH BRAKE LIGHT
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.
GCS CS STYLE REAR F1 VS SUBISPEED
The rear fog light were built to our specifications for USDM vehicles. This means there is not a 7440 socket in the bottom and the brake / fog lights have a dual intensity function so that when run at night, the fog light is dimmer than the F1. This allows drivers to easily differentiate fog vs brake functions. However, this model sticks closely to the CS style rear fog lamp and is massed produced at a lower price point. Also note that the F1 function does not work when the fog light function is not in use*. There are various ways to wire this up that can change it into a solid brake light with no fog vs F1.
