Can You Put LED Bulbs in a 2021 Ford F-600 Super Duty?
For a Ford 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 H13 low beams, as they see the most use. Adding a matching LED kit later will complete the look and ensure consistent lighting performance. Don't forget the 9140 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
