As advertised!
After installing the H13-HLV4-1 LED headlight Kit the high-beam relay did not function properly in conjunction with the fog lights. Took a chance with these,(plug and play) units and (BINGO) the problem was gone. Lots of plastic-ties to bundle-up and secure the wiring! Like it!
Perfect
I'm not 100% sure this was necessary for a 2008 F-150. But from other reviews, forum posts, and YouTube videos of people with similar models I felt it would be a safe bet to buy this and avoid hiccups down the road. Glad I did, no issues with the on-board computer and my brights function correctly too!
