Black U-Shaped LED Projector Headlights Pair for GMC Sierra 1500 (2014-2018) / 2500 HD 3500 HD (2015-2019)

Update a 2014-2018 Sierra 1500, or a 2015-2019 HD, with a black full-LED projector pair and a U-shaped LED daytime running light. You get driver and passenger assemblies with a clear lens, black housing, and an amber side marker. High beam, low beam, turn signal, and the U-shaped DRL are all LED — no halogen bulbs to transfer. A DRL adapter harness is included; you may need to connect it at the fuse box (a common location is fuse F39 or F40) so the daytime running light operates.

Installation: GMC Sierra 1500 (2014-2018) and 2500 HD 3500 HD (2015-2019)

On these trucks the headlight is typically easier to remove after the grille or the bumper cover is loosened, because some of the mounting bolts sit behind the fascia. The U-shaped daytime running light may also need the included adapter harness tied into the fuse box. Professional installation and beam aiming are recommended. Switch off the lights and ignition, set the parking brake, and disconnect the negative battery cable before you start.

1. Loosen the grille or the bumper cover so you can reach the headlight bolts behind the fascia.
2. Support the lamp, remove the bolts, and pull the assembly forward. Disconnect the factory harness.
3. Connect the new LED headlight to the factory connector. Route the included DRL adapter harness and connect it at the fuse box as shown in the guidelines (a common location is fuse F39 or F40) so the U-shaped daytime running light operates.
4. Seat the housing, reinstall the bolts, and repeat on the other side. Refasten the grille or bumper cover.
5. Reconnect the battery and check high beam, low beam, turn signals, and the U-shaped DRL. Aim the headlights on a level surface before driving at night.

Frequently Asked Questions

Which trucks does this pair fit?
GMC Sierra 1500 (2014-2018) and Sierra 2500 HD and 3500 HD (2015-2019) with factory halogen headlights. Compare your current housings with our photos before ordering.

Will it fit factory HID or factory LED DRL headlights?
No. These assemblies replace factory halogen headlights. They will not fit factory HID or xenon lamps, or trucks that already have factory LED daytime running lights.

Will it fit a 2014 Sierra HD or a 2019-up 1500?
No. 2014 Sierra HD uses the previous-generation headlight, and 2019-up Sierra 1500 uses a different body. Do not order this pair for those trucks.

Are bulbs included? Do I need the DRL harness?
No separate bulbs are required — high beam, low beam, turn signal, and the U-shaped daytime running light are all LED. The DRL may need the included adapter harness connected at the fuse box (a common location is fuse F39 or F40) so the daytime running light operates.
