Give your GMC Sierra 2500/3500 HD a premium lighting upgrade with the Diode Dynamics Sequential LED Sidemarkers. These plug-and-play replacements transform your factory fender lights with a dynamic startup sequence, full LED illumination, and a sequential amber turn signal that adds both modern styling and increased visibility. Installation is simple using the included wiring harnesses with no cutting or splicing required.

Unlike factory sidemarkers that only illuminate a small section, these feature a dual-lens design that lights the entire housing for a smooth, uniform glow. OEM-grade materials, factory-style connectors, and built-in circuit protection provide reliable, flicker-free performance, while integrated breather vents help keep moisture out for long-lasting durability.

Available with Amber , Smoked , or Clear lenses, you can choose the look that best matches your truck. All three options produce the same bright amber LED illumination and sequential turn signal while giving your Sierra HD a clean, custom appearance!
