Introducing the GMC Sierra 2500 Side Marker Light Assembly by Diode Dynamics, featuring LED Sidemarkers HD in a sophisticated smoked color for the `20-`21 model. These LED sidemarkers are specifically designed for a sharp, bright, and unique illumination, perfectly complementing the rugged yet sleek exterior of your GMC Sierra HD.

Our side marker light assembly offers an upgraded style with its plug-and-play capabilities, making it a hassle-free replacement for factory fender lights. Each sidemarker is engineered to illuminate the entire width of the housing, providing a distinctive, brighter appearance that enhances the vehicle's overall look. The dynamic startup sequence with its animated effect, starting from the center and spreading to either side, adds an eye-catching feature every time you activate the lights. For even more functionality, the optional sequential turn signal feature uses a plug-and-play wiring harness to create a sequencing amber pattern, enhancing safety and visibility.
