2020-2026 GMC Sierra 3500HD Lighting

Lighting upgrades engineered for the 2020-2026 GMC Sierra 3500HD, covering SLE, SLT, AT4, and Denali trims. Shop headlights, LED fog lights, switchback DRLs, cab roof markers, bed lighting, and full light bars from Morimoto, Diode Dynamics, Baja Designs, and Rigid Industries.

Will these lights trigger a CAN-bus error or flicker on the dash? No. Our LED headlight and fog kits ship with the correct anti-flicker harnesses or load resistors for the Sierra HD electrical system, so there is no hyperflash, no bulb-out warning, and no dash error.

Verified fitment for your Sierra 3500HD, no guesswork.
