Compatibility

Listed for matching 2016–2019 Chevrolet Silverado and GMC Sierra tail light configurations. For 1500 trucks, compare against the 2016–2018 body style and any 2019 carryover LD/Limited configuration. Selected 2500HD/3500HD applications retain that body style for 2019. Do not assume compatibility with the redesigned 2019 1500.

Factory incandescent and integrated-LED lamp systems use different wiring. These harnesses have the three bulb sockets shown in the photos; match the original harness number, socket arrangement, connector color, pin layout and wiring length. They are replacement socket harnesses, not LED conversion adapters.

Inspect the vehicle-side wiring and lamp housings for corrosion or heat damage before fitting. Follow the vehicle wiring diagram and test tail, brake, turn-signal and reverse functions after installation. Professional installation is recommended.
