Using this light plate is easy. First, gather all the necessary tools and your chosen driving lights (which you'll need to buy separately). Find a flat and safe place to work on your 2015 - 2021 Subaru WRX/STI. Locate the appropriate spots on your car's front where the light plate will fit, as it's specifically designed for this model. Then, simply bolt the light plate onto your vehicle. When mounting the lights, make sure they are securely fastened. As for maintenance, regularly check the bolts to ensure they haven't come loose. Wipe down the light plate with a clean, dry cloth to keep it looking good. The black powder - coated finish helps protect it from abrasion, but try to avoid rough contact with sharp objects to keep it in top condition.
