2017 GMC Sierra 2500 HD Tail Lights

Genuine GM tail lights for the 2017 GMC Sierra 2500 HD, at wholesale prices. Tail lamp part numbers split on trim and on whether the vehicle has LED or incandescent lighting. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

Symptoms to look for

Moisture in the housing, a cracked lens, or an out bulb that keeps recurring. On a heavy duty pickup, two trucks with the same badge can take different parts once cab style and drivetrain are accounted for.

What sets these apart

• Returns without a fight. We would rather fix a tail lights order than argue about it.
• Covered by GM. On tail lights that coverage is worth more than the price gap.
• Real wholesale. The same tail lights your dealer sells, at a fraction over our cost.
• OEM, not lookalike. With tail lights the difference shows up on installation day, not in the photo.

Ordering correctly

Genuine GM parts carry the factory part number, so supersessions are documented rather than guessed at. Run your VIN first. One vehicle can list several nearly identical parts and only one is correct. Because we ship centrally, a heavy part costs less delivered here than from a coastal seller.
