Fits: 2015 thru 2019 GMC Sierra 2500HD/3500HD LML/L5P Duramax Diesel

We live, eat, and sleep headlights. While the highly anticipated Sierra LED headlights from Morimoto cost a bit more relative to other options in the aftermarket; as the saying goes "you pay for what you get". We've seen it all, and their fit and finish is far superior to everything else out there. Guaranteed. Lets take a look at some of their stand out features below.

Sequential LED DRL: Game Changer! The Morimoto LED daytime running light is powered by Osram 5000K LEDs and is insanely bright, easily visible during the day. A separate optic that's dedicated to the turn signal function uses amber LED's to produce a full sequential turn signal, or a more traditional on-off style signal as well depending on how you set it up. The C-Shaped DRL is ran through an advanced light-pipe style optic to ensure the intensity is there no matter what viewing angle you're looking at them from.

DOT APPROVED: Make no mistake, these will produce a much different [better] result than slapping some LED replacement bulbs into your stock housings. Their quad-projector optics meet & exceed all SAE, DOT, and FMVSS108 regulations when aimed properly...and that's easy to do with their integrated vertical/lateral adjusters.
Wiring is easy too! The LED headlights are designed to work on your GMC Sierra with stock halogen or HID headlights 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.

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. The PPS plastic housing is light-weight and much stronger than comparable alternatives. The die-cast aluminum heat-sinks inside the housings provide more than an adequate amount of cooling for the OEM grade Osram LED chips that produce the light.

Amazing. At least in our opinion! The subtle elements incorporated in their design are more than enough to make them stand out, but they're clean enough to be considered top of the line original equipment to those who don't know any better. The piano black trim and amber side markers keep the color scheme clean, and the 3in diameter Bi-LED kuria-optic projectors allude to the OEM Style that clearly inspired the design.
