GMC Headlight Repair
GMC headlight repair by mail works on the GMC headlight your Sierra or Sierra HD already has, when an LED section goes out or condensation stays behind the lens. Ship it in from anywhere in the U.S. after a free quote that says what can be repaired.
From $400 per headlight — final price in your free quote. Packing and shipping instructions come with your quote.
GMC Sierra headlight: LED section out or moisture
On a Sierra pickup, a dark LED section or droplets that won't clear usually point to the headlight itself rather than the bulb.
If an LED has gone out, the repair is done inside your original unit, as in LED Headlight Repair. Tell us the symptom and we'll confirm whether the LED or DRL module can be repaired.
GMC Sierra HD headlight on the 2500HD and 3500HD
If both headlights on a 2020-or-newer Sierra 2500HD or 3500HD show condensation behind the plastic lens, say on a 2024 truck, have the seals looked at before you buy a new pair.
Whether it is a Denali, an AT4 or a work truck that tows every day, send the trim with your photos so the quote matches your unit.
If your model year has an open recall or an extended warranty from the manufacturer, check with your dealer first.
Other heavy-duty pickups and semis are listed on Truck Headlight Repair.
Condensation behind the lens
A thin haze that clears once the lights are on is normal. Droplets, streaks or water at the bottom of the lens that stay for days mean a seal has failed.
The headlight is opened, dried and resealed, as in Headlight Condensation Repair & Resealing.
Halogen bulb or the headlight itself
On a halogen headlight, a dark beam is usually the bulb, so start there. Aftermarket LED bulbs and the truck's wiring are not something we repair; a local shop is the right stop for those.
A cracked or chipped outer lens is a different job. Tell us what happened to the lens and we will confirm whether the outer lens can be replaced on your headlight, as in Headlight Lens Replacement Service.
Before you order a GMC headlight replacement
Repairing the unit on your Sierra keeps:
- The factory fit against the grille, hood and fender
- The same light signature on the left and the right
- The headlight you already own, with only the failed part replaced
