As with any car, you can get rocks and debris that gets kicked up and hitting the front of your vehicle. This can result in paint chips on your front bumper and hood. It can also cause cracks and breaks in your headlight, turn signal, and fog light lenses. When I purchased my BMW E46, it already had a broken corner light lens. Replacing the corner light is actually quite easy, although if you don’t know how to remove the corner lens, it may be frustrating to deal with.
