Description
Upgraded Lighting Performance. The Diode Dynamics Standard LED Side Marker Lights in Amber replace factory fender lights for improved brightness and style. These lights enhance vehicle visibility and offer distinctive amber illumination with a unique dynamic startup sequence that animates from center outward, ensuring both safety and appealing aesthetics.
Construction and Appearance. Crafted with automotive-grade ABS bases and UV-stable PMMA lenses, the sidemarkers feature a dual-lens design that diffuses light evenly across the housing for full illumination. Materials and manufacturing processes meet OEM standards, delivering durability, impact resistance, and a weather-tight seal to withstand harsh environments.
Installation. Installation is straightforward, requiring basic tools and no drilling or vehicle modifications. The factory fender liner must be removed using included or compatible clips, making the process suitable for most users within 1-2 hours.
Warranty. These sidemarkers come with a 3-year limited replacement warranty, ensuring dependable performance and product confidence.
Application. Designed specifically for the GMC Sierra 3500 HD models from 2020 through 2026. Note: The sequential version is not compatible with the 2023 Denali Ultimate and AT4 HD trim levels.
