Can You Put LED Bulbs in a 1991 Ford Explorer?
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 9004 low beams, as they see the most use. Adding a matching 194 LED kit later will complete the look and ensure consistent lighting performance.
