Using this Rally Innovations light bar is easy. First, gather your driving lights (which you'll need to buy separately). Make sure they are up to 6.5 inches in diameter and 0.5 inches in depth. Then, simply bolt the lights onto the light bar. Next, install the light bar on your 2015 - 2021 Subaru WRX or STI. It's designed to fit nicely with the OEM bumper. As for maintenance, you don't have to worry too much. The textured black powder - coated finish helps protect it from rust. But it's still a good idea to clean it regularly with a mild soap and water. Avoid using abrasive cleaners as they might damage the finish. Also, when you're installing or removing the lights, be gentle to prevent any bending or breaking of the mild steel tubing.
