Overview
For the 2014-2018 GMC Sierra 1500, the 2019 Sierra 1500 Limited and the 2015-2019 Sierra 2500HD and 3500HD, this smoked red LED set keeps the factory lamp outline and its factory turn-signal logic.
Highlights
- Smoked red signature runs a red light element around the outer edge of the housing, with the reverse section set in the middle of the lamp.
- Factory-style turn signal shares the red lighting zone with the brake light and flashes red, the same way GMC wired the original lamp. There is no separate amber indicator and no sequential sweep.
- Startup animation runs the lighting sequence once when you fire up the truck.
- Brighter brake and reverse lighting improves rear visibility so drivers behind you can react more clearly in traffic, parking, and low-light conditions.
- Adapter harness for 2014-2015 trucks is included in the box; 2016 and later trucks plug into the factory connector directly.
- Weather-resistant construction helps protect the lens, housing, and internal electronics from rain, dust, and road conditions.

Frequently Asked Questions
More answers in our FAQ.
Are these tail lights street legal?

How hard is installation?
They use your factory mounting points and plug-and-play connectors — no cutting or splicing. Install time depends on your vehicle; we recommend professional installation.
