Upgrade your 2008-2016 Ford Super Duty with GTR Ultra Series 3 LED headlight bulbs. These bulbs are HR Tested, meaning they've been installed and tested to ensure they fit and work right out of the box. Built with care, the Ultra Series 3 uses custom 8050 LED chips and precise design to focus light where you need it most - on the road, not in the air. Even though the bulbs are smaller, they’re powerful, putting out 3,300 lumens of bright, clear light. Thanks to Thermal Separation Technology, they stay cool and last longer. Installation is easy because of the compact size, and there’s no need to worry about performance. These bulbs are backed by a lifetime warranty, so you can trust they’ll last. At Headlight Revolution, we’ve tested these bulbs ourselves, so you can be confident you’re getting top quality without the guesswork.
