Fitment Notes: 2014-2018 GMC Sierra
It’s surprising that GMC continued to use old-fashioned headlights on the Sierra until the 2020 revision of the HD trucks. Luckily, the new Morimoto XB LED headlights offer numerous benefits. They look fantastic, are well-made, have an almost unlimited lifespan, and outperform other options. Upgrading to these headlights is an excellent way to improve performance and give your Sierra’s front end a facelift at the same time.
Morimoto’s Sierra LED headlights may cost more than other aftermarket options, but you truly get what you pay for. As headlight experts, we’ve seen it all, and we can confidently say that Morimoto’s fit and finish are far superior to other options. Their standout features include the Sequential LED DRL, powered by Osram 5000K LEDs, which is exceptionally bright and visible even in daylight. Additionally, their C-shaped DRL is enhanced with an advanced light-pipe style optic, ensuring consistent intensity from all angles. Morimoto’s quad-projector optics are DOT approved and exceed all SAE, DOT, and FMVSS108 regulations when correctly aimed.
Sequential LED DRL
Morimoto’s Sequential LED DRL is a game-changer. Powered by Osram 5000K LEDs, it’s incredibly bright and visible during the day. The turn signal function uses a separate optic with amber LEDs that produce a full sequential turn signal or a traditional on-off signal, depending on your preference. The C-shaped DRL runs through an advanced light-pipe style optic, ensuring consistent intensity from all viewing angles.
Morimoto’s LED headlights far outperform simply replacing your stock headlights with LED bulbs. Their quad-projector optics meet and exceed all SAE, DOT, and FMVSS108 regulations when correctly aimed. The integrated vertical/lateral adjusters make proper aiming a breeze. These headlights are easy to install, with no error codes, flickering, hyper-flashing, or radio interference. Plus, they won’t void your factory warranty.
Installing Morimoto’s LED headlights on your GMC Sierra is a breeze. Designed to work with stock halogen or HID headlights, they plug into your factory connectors and come with all necessary connectors, rubber seals, and pigtails for a plug-and-play installation. You won’t encounter error codes, flickering, hyper-flashing, or radio interference. Removing them is just as easy, and they won’t void your factory warranty.
Morimoto’s LED headlights are built to last. Their UV-coated polycarbonate lens ensures that your truck’s new headlights will look like new for years to come. The PPS plastic housing is lightweight yet stronger than comparable alternatives, and the die-cast aluminum heat sinks inside the housings provide ample cooling for the Osram LED chips that produce the light.
In our opinion, Morimoto’s LED headlights look amazing. The design incorporates subtle elements that make them stand out, yet they’re clean enough to pass for top-of-the-line original equipment. The piano black trim and amber side markers keep the color scheme clean, and the 3-inch diameter Bi-LED Kuria-optic projectors are reminiscent of the OEM style that inspired the design.
