The Diode Dynamics LED Sequential Sidemarkers in Smoked fit the 2020-2023 GMC Sierra 2500HD and replace the factory fender lights with a fully-illuminated, animated LED upgrade.
Plug-and-play install with an included wiring harness for sequential turn signal function.
Product Overview
These LED sidemarkers swap directly into the factory fender light location on your Sierra 2500HD. The dual-lens design illuminates the entire housing width for an even, bright glow no factory bulb can match.
Every startup runs an animated amber sequence from the center outward before settling into running light mode. The sequential option uses the included plug-and-play harness off the headlight connector to add a sweeping turn signal pattern.
Smoked lenses give the housings a dark, tinted look that pairs well with black or grey trucks.
