Choose from three lens color options to match your vehicle or preference. OEM Grade. Unlike other sidemarkers on the market, Diode Dynamics lamps use OEM-grade retroreflector optics, which provide required the reflective safety and a clean, premium appearance when off, unlike "diffuser" or plain flat lenses without any reflective features. The units themselves are designed directly from OEM CAD data for a perfect fit, and the connector plugs 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.
