I have 4" round lights mounted in my rear off-road bumper. Wanted to run amber color lights to utilize when in dust to help upcoming drivers see me through the dusty conditions. These Lamin-x amber covers are fantastic! Nice bright amber color and the film is thick so that it won't wear out quickly. They install very easy and finished product is exactly what I was looking for. Washed my truck and the film holds up great without dulling from washes.
