Game Changer: The game has just changed, again. If you've got a 2021+ F150 and you paid extra for the OEM LED headlights, well... hindsight hurts doesn't it? If you're thinking about buying one, the Morimoto XB LED headlights for the 2021+ Ford F150 should be the first thing on your wish list. There is only one problem with that: OEM LED Trucks: If your new F150 has the OE Reflector-LED headlights, you will need to buy the LF498H adapter harnesses to ensure full-functionality with the more complex Linbus system that digitally controls the different modes for the headlights. This Harness: Will adapt the new Morimoto XB LED headlights for the 21+ F150 onto trucks that came stock with the OE Reflector-based LED headlights. Everything will be fully plug n play and work normally. It will not work on trucks that have the dual-projector lights with AFS and auto-leveling though.
