The Morimoto XB LED Headlights are hands down the best headlight housing replacement available on the market for the Tundra. Their triple Bi-LED setup produces a well-defined beam pattern with a great amount of width, intensity, and a proper distribution of light. In our testing, they even outperformed the expensive OEM LED headlights! These are much more than an aesthetic upgrade, they will illuminate the road much more effectively in both low, & high beam. If the optical upgrades weren't enough, they also have a badass start up sequence. When the Daytime Running light kicks on, the projectors illuminate in a two-stage sequence before turning back off. A video is worth a thousand words, so to see what we're talking about just watch our video feature covering the lights! The LED daytime running light is powered by Osram 5000K LEDs and is insanely bright, easily visible during the day. The also have the trademark sequential turn signal too, which can also be setup to run as a solid on/off style. Wiring is easy too! The LED headlights are designed to work on your Toyota Tundra without any modifications. They will plug into the factory connectors for the stock headlights and each assembly includes all necessary connectors, rubber seals, and pigtails for a plug n play install. No error codes, no flickering, hyper-flashing, or any of that. These lights can easily be removed and will not void your factory warranty. DOT Approved: Their triple-projector optics meet & exceed all SAE, DOT, and FMVSS108 regulations when aimed properly which is easy to do with the vertical/lateral adjusters that are pre-set to OEM specifications. Their UV-coated polycarbonate lens will resist the test of time, ensuring your truck's new headlights will look good as new for many years to come.
