Features Plug-and-play compatible with GMC Sierra HD 2024+ fender lights Dynamic startup sequence with animated effect Fully-illuminated housing, with dual-lens design for an even glow Optional Sequential turn signal feature, with plug-and-play wiring harness OEM-grade construction and perfect fitment Engineered and assembled in USA Overview Upgraded Styling. These LED sidemarkers are a plug-and-play replacement for the factory fender lights, illuminating the entire width of the housing for a distinctive look and brighter appearance. Choose from three lens color options to get the look you're after. Unique Startup. Both the standard and sequential models feature a unique startup sequence. Every time the sidemarkers turn on, they illuminate in an intense amber color starting from the center then spreading to either side. Once they are completely illuminated, they gradually return to a running light mode. Sequencing Turn Signal. Our sequential option provides an upgrade in functionality. Anytime you hit your turn signal, the sidemarkers illuminate in a sequencing amber pattern to indicate signaling! The sequential option uses the included plug-and-play harness to power the fender lights using the headlight connector. Options Amber: These match your original sidemarkers, and are DOT/SAE compliant. Smoked: A dark appearance, great on black and grey vehicles. Clear: These are clear in color, but still have the retroreflector optics.
