Can You Put LED Bulbs in a 2007 GMC Sierra 1500 HD Classic?
For a GMC built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection. We recommend starting your upgrade with the 9006 low beams, as they see the most use. Adding a matching 9005 LED kit later will complete the look and ensure consistent lighting performance. Don't forget the H10 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
