Using these headlights is a breeze. They come with a plug - and - play wiring system, so you can easily install them on your 2009 - 2014 Ford F - 150 with OE incandescent setup. Just connect the wiring and you're good to go. Remember, if your truck has OEM 3157/4157 front turn signal bulbs, you'll need to buy a set of 7443's separately. And these headlights aren't compatible with OE LED. For maintenance, since they have a UV - coated polycarbonate lens, they'll keep their shine for a long time. Just clean them regularly with a mild soap and water solution to keep them looking great. They have a 5 - year warranty, so you can use them with confidence on the road.
