Using this Subaru reflector cover kit is straightforward. First, make sure your WRX is parked safely on a flat surface. Then, carefully remove the existing rear reflectors. Next, take the parts from the kit and install them in place of the removed reflectors. It's a good idea to follow a removal video for detailed steps. Remember, this kit is only for off - road use because in the US, rear reflectors are required by law. When it comes to maintenance, keep the covers clean with a mild soap and water solution. Avoid using harsh chemicals that could damage the finish. Check the installation periodically to ensure all parts are still firmly in place.
