GMC Sierra Side Marker Light Assembly - Diode Dynamics - Sequential Sidemarkers - Clear - `24-`27. Plug-and-play LED replacements for your factory fender lights, providing a crisp, full-width amber glow with a unique startup animation.

Designed for GMC Sierra HD 2024+, these clear-lens sidemarkers use OEM-grade retroreflector optics and a dual-lens design for uniform output across the housing. Both standard and sequential versions include a distinctive power-on sequence; choose the sequential model for animated turn-signal indication using the included plug-and-play harness. Engineered and assembled in the USA, the housings match OEM fitment and install without cutting or splicing. Each kit includes four sidemarkers, two harnesses, ten fender clips, and four rubber plugs.
