Symptoms to look for

Moisture in the housing, a cracked lens, or an out bulb that keeps recurring. On a heavy duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

Buying OEM, briefly

• Factory warranty. Genuine tail lights carry GM coverage aftermarket cannot match.
• Dealer parts, not dealer prices. Compare our tail lights pricing against a counter quote.
• Genuine GM only. Every tail lights listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the tail lights before the box leaves.
• Central shipping origin. Dallas keeps tail lights transit times short nationwide.

Ordering correctly

Factory parts are built to the tolerances the vehicle was engineered around, not copied from a worn sample. A photo is rarely enough to order from. The VIN takes seconds and removes the guesswork. Freight is quoted at what it actually costs, not inflated to subsidize a headline discount.
