If you're looking to give your GMC Sierra 2500/3500 an upgrade in styling and appearance, this is the perfect way to do it! 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. These lenses 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. OEM Grade. Unlike other sidemarkers on the market, these sidemarkers were designed for OEM standards of quality, using automotive-grade plastic materials, UV-stable lenses, and quality connectors. The dual-lens design uses an inner diffusing lens combined with an outer lens, for an even, uniform glow. The units themselves are designed directly from original CAD data for a perfect fit, and use OEM-grade connectors that plug right into the factory socket. Reliability. These LEDs are designed with newer constant-current circuitry and transient voltage protection. These features, found in factory-installed lighting components, protect the circuit over time, ensuring years of flicker-free performance. They also include a breather vent, to prevent pressure buildup and maintain a strong weathertight seal for years to come. Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting. Unlike all other LED distributors, we assemble and engineer products in the United States, for high quality and fast time-to-market of the newest and brightest LED technologies. We pride ourselves in offering only quality LED products, that will exceed your expectations. Please contact us if you'd like to discuss your lighting project!
