Features: Modern LED replacements for factory sidemarkers. Increased output, with unique styling. OEM-grade retroreflector optics. Available in red, clear, or smoked lens options. Engineered and manufactured in USA. Upgraded Styling: If you're looking to give your EU/AU Mustang an upgrade in styling and appearance, this is the perfect way to do it! From the factory, the EU/AU Mustang has reflectors that do not light up. With the included harness, you'll be able to upgrade your sidemarkers to illuminate with hundreds of LEDs, for a modern and unique appearance. 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. Options: All sidemarkers illuminate in bright red, but there's three colors of lenses. Choose the one that fits your style! 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.
