Harley-Davidson® LED Lamps are brighter and whiter in color and provide a superior light pattern over standard incandescent lamps. Compared to the yellow light of a traditional halogen bulb, the LED lamp produces a "Daylight Color Impression" that appears more natural to the user. Headlamps feature 2 horizontal "D" shaped lenses that focus light into a pool in front of the motorcycle, and separate high beam and low beam projector lenses that provide a focused beam of light in front. 4" LED Auxiliary Lamps feature 3 "D" shaped lenses that focus the light, and provide a matching appearance to the LED headlamps. The solid-state LEDs are designed for long life, and the shock- and vibration-resistant lamp assembly mounts into existing light housings. Installation is quick and easy, and the plug-in lamps connect to the factory headlamp wiring. No external ballast or complicated wire harness is required. The LED lamps are DOT approved for use in all 50 states.
