DOT APPROVED: Make no mistake, these will produce a much different [better] result than slapping some LED replacement bulbs into your stock housings. Their LED-specific reflector optics meet & exceed all SAE, DOT, and FMVSS108 regulations when aimed properly...and that's easy to do with their integrated vertical/lateral adjusters.
PLUG-N-PLAY: 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 radio interference. They can easily be removed, and will not void your factory warranty.
