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.
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.
All sidemarkers illuminate in bright amber (front) and red (rear), but there are three colors of lenses. Choose the one that fits your style!
Amber/Red: Also called OEM, these match your original, and are DOT/SAE compliant in both illumination and lens color.
Smoked: A dark appearance, great on black and grey vehicles.
Clear: Blends nicely on white and silver. These are clear in color, but still have the retroreflector optics.
