USDM vehicles from the factory didn't come with a rear fog light, just a plastic cap on the rear bumper. This fog light adds both extra lighting and a cool style to your 15 - 21 WRX and STI. It combines fog light and brake light functions. The brake light has an F1 - Style flasher, giving your custom Subaru a racing look. You can choose from different lens and housing colors to match your vehicle. It can be wired in various ways for different functions. Installation requires minor splicing, and a plug - and - play harness is available separately. The F1 brake light function works when the fog light is on. Wiring details: Red wire is for brake light positive, black wire is for ground/negative, and green wire is for running light positive. Note that the F1 brake function only works when the fog light and running light are on. For the Crosstrek, the wiring can be routed directly to the tail light with connectors outside the vehicle. What's included: F1 Style Fog Light Assembly and Mounting Hardware. The Noble Performance Plug and Play F1 Light Harness can be purchased separately.

Using this GCS CS - Style F1 LED rear fog light is easy. First, check if your Subaru model (2015 - 2021 WRX, 2015 - 2021 STi, or 2013 - 2017 Crosstrek) is compatible. When installing, you'll need to do some minor splicing. If you want an easier installation, you can buy the plug - and - play harness separately. Connect the wires as follows: the red wire to the brake light positive, the black wire to the ground/negative, and the green wire to the running light positive. Remember, the F1 brake light function only works when both the fog light and running light are on. For the Crosstrek, route the wiring directly to the tail light connectors outside the vehicle. To maintain this fog light, keep it clean with a soft cloth and mild cleaner. Avoid using abrasive materials that could scratch the lens. Check the wiring regularly to make sure there are no loose connections or signs of damage. If you notice any problems, have it inspected by a professional.
