Led Rear Lamp Assembly for 2019-2024 GMC Sierra 1500/2500 HD/3500 HD

Upgrade your GMC Sierra 1500 (2019–2024), 2500 HD (2019–2024), or 3500 HD (2019–2024) with TT-ABC’s LED Rear Lamp Assembly, engineered specifically for factory full-LED equipped trucks. This all-in-one unit integrates brake lights, reverse lamps, and running lights into a single sealed housing, eliminating the need for multiple fixtures or added bulbs.

Crafted from military-grade ABS plastic and UV-treated polycarbonate lenses, each assembly delivers high-intensity illumination for superior road visibility—even in rain, fog, or off-road conditions. Passive cooling fins and hydrophobic coatings prevent fogging and overheating, maintaining clear optics across a wide temperature range.

True plug-and-play installation harnesses your truck’s existing connectors—no splicing, drilling, or resistors required—while built-in current-limiting resistors ensure proper CAN-bus communication and prevent hyper-flash. Backed by a one-year limited warranty and 24/7 technical support, TT-ABC makes upgrading your Sierra’s rear lighting both simple and secure.
