Can You Put LED Bulbs in a 2001 GMC Sierra 1500 HD?
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 LED low beams, as they see the most use. Adding a matching 74 LED kit later will complete the look and ensure consistent lighting performance. Don't forget the 880 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
