good but i need to return for frosted onlyu

These lights make a big difference in the look of the new GMC's. Boost has an excellent video showing you how to put them on. I did find out the you can put the passenger side front light on without taking the fender liner out. If you come in from the top you can do it through the fender. It is a little harder to line the screws up but takes a lot less time.

100% awesome experience. Thank you
