Convert any H4 LED Headlight to work with any 2007-2018 JK Wrangler with RT Off-Road’s LED Headlight Adapter Harness. Included is a pair of harnesses that convert the H4 connector to the factory JK H13 connector. As an added measure, we built an anti-flicker module into each harness to eliminate the annoying flicker that is seen when low quality LED headlights are installed on a JK. These harnesses will provide a plug-and-play installation with a long life.
