WHATS INCLUDED: 1 Pair of Headlight Assemblies (Wiring Included) WARRANTY: 5-Year Warranty (Void if housings are opened or modified.) DOT APPROVED: Make no mistake, these XB LED headlights will produce a much different [better] result than slapping some LED replacement bulbs into your stock housings. Their triple-projector optics meet & exceed all SAE, DOT, and FMVSS108 regulations when aimed properly... and that's easy to do with their integrated adjusters. PLUG-N-PLAY: Wiring is easy too! The XB Silverado LED headlights are designed to work without any modifications. These 2020+ Silverado HD headlights 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. SEQUENTIAL LED DRL: Game Changer! Their LED daytime running light is powered by Osram LEDs and is insanely bright, easily visible during the day. Even the high-end OE LED headlights have oldschool incandescent turn signals, so the sequential LED turn signal on the XB is a big upgrade over the original equipment signals too! The sequential mode can also be disabled for those who prefer something a bit more conservative, and want a solid on/off flash instead.
