GCS Rear Fog Light Combination Lamp

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.

Fog Light

This unique light will increase viability at night and especially under foggy conditions.

It can be wired to light up with your parking / headlights or just your fog lights (with fog light extension harness).


Brake Light

JAB... Just another brake (light). Wire this GCS lamp into your brake light wiring and it will emit a bright red light when stopping. This light is brighter than the fog light function. Therefore people behind you will definitely know when you're braking versus simply driving with your lights on.


Reverse Light

Here's a new function which can come in handy. The GCS rear fog light has a row of white lights to aid when backing up the vehicle. Additional light will help you see behind the vehicle and alert others.


Models

  • Smoked lens
  • Clear lens
  • Red lens
  • Matte Black With Clear Lens

Wiring

Red Wire (socket) - Brake Light Positive
Black Wire (socket) - Ground / Negative
Green Wire (loose) - Running Light Positive
White Wire (loose) - Backup Light Positive


OPTIONAL Fog Light Wiring Splitter / Extension

If you want to wire this so that it only comes on with the fog lights you'll find yourself using a pretty long run of wire.

We've made a quick connect kit which will split the wires to the passenger side fog light. Just run the wire under the driver's side fender liner, into the vehicle, and along the door sills back to the trunk of the vehicle. The insulated connectors will be placed on the F1 light harness and extension. Just connect them together and you'll have a functioning rear fog light.

Includes splitter and extension with two pairs of connectors. The plug for the female end is not pre-attached so that the wires can easily be run through grommets in the firewall area. To purchase this addition, click here.


OPTIONAL Plug and Play Harness

This harness speeds up the install process. The stock wiring harness in the WRX / STI can be hard to crimp as the area is tight. Also owners who wish to return their setup to stock at any point and time can do so easily with this harness.

The harness has OEM style connectors on both ends which allows you to install this in-line with the factory wiring. 4 extensions allow you to connect the aftermarket fog / F1 lights.

  • Black - Ground (-)
  • Red - Brake Light (+)
  • Orange - Parking / Running Light (+)
    [Hooks up to green wire on GCS Rear Fog / Brake / Reverse Light]
  • White - Reverse Light (+)

  • F1 Style Fog Light Assembly
  • Mounting Hardware
  • Wiring Harness with Connectors
  • Fog Light Wiring Splitter / Extension (optional)

FAQ

The bumper cover does not need to be removed in order to install this product. Simply undo the fasteners at the bottom of the bumper cover so you can gain enough access to knock out the factory plastic cap.

We highly recommend covering the lens of the new fog light casing with painter's tape or something similar during installation. This will prevent scratches while you maneuver it into position.

Our video will help your through the installation process. However, for reference, the OEM tail light wiring is as follows:

  • Black Wire - Negative aka Ground (wire to black wire on the new harness with socket on the end)
  • Brown Wire - Brake Light Positive (wire to red wire on the new harness with socket on the end)
  • Black Wire w/ White Stripe - Fog Light Positive (wire to loose green wire)
  • Brown Wire with Yellow Stripe - Reverse Light Positive (wire to loose white wire)

If you use the fog light extension harness, the negative and fog light wires will be supplied by that harness. You will only use the OEM tail light harness for the brown wire (brake light positive).

You can wire the lamp as a solid brake light only. You would do this by connecting the fog light wire (red) on the lamp to the brown wire on the OEM brake light wire (brown). It would be dimmer than the F1 style lamp though.

While many states allow brake lights that flash and then turn solid, some do not. Please refer to your local laws pertaining to this feature.

It is not required that you hook up the brake light wiring. You can run the product as a rear fog light only.

Installation Instructions

Explosion Diagram

Installation is simple. Follow the diagram for installing the housing. This product follows the same basic design as the Subaru OEM piece.

Wiring

Use the driver's side tail light harness to provide power to the JDM fog light. The following lists which wires on the tail light harness you can use to tap for a power source.

Black Wire - Negative aka Ground (wire to black wire on the new harness with socket on the end)

Brown Wire - Brake Light Positive (wire to red wire on the new harness with socket on the end)

Black Wire w/ White Stripe - Fog Light Positive (wire to loose green wire)

Brown Wire with Yellow Stripe - Reverse Light Positive (wire to loose white wire)

Wiring this to the tail light for use as a fog light will result in the light being on whenever the parking lights or low beams are on. There are grommets under the carpet which are covered with little stickers which you can use to pass the harness from the outside of the vehicle to the inside.

  1. Looks Awesome

    By Christopher November 03, 2018

    I love the way they make the car look, especially at night. Love the multifunction design. Who ever thought about this is a genius. It’s easy to install. Took me about 30 minutes. I recommend these lights. You won’t regret it.

  2. Great product

    By Chris July 06, 2018

    I got the smoked version for my wrx and it is awesome, I had a little trouble lining up the holes so I had to use a washer to straighten the light with the bracket. After a year it is still going strong.

  3. Great product

    By Zach November 26, 2017

    With no wiring experience, the install took 15 minutes. Definitely love it.

  4. easy install, quality upgrade!

    By Stephen November 13, 2017

    Took me about 30mins to install the fog light. The bolts holes do not line up with the bracket. If you are buying this for a crosstrek you will have to bore out the hole a little to align it with the bracket. The screws provided are just a little too short, luckily I had some server rack screws that were just long enough to secure the light in place. Also you will have to cut out some of the body to get the light to sit flush.
