Elliptical projector light produces a razor sharp horizontal cutoff beam pattern. This pattern eliminates reflected light coming back into the driver’s eyes and stops stray light from offending oncoming traffic. Switching between driving lamp and projector lamp allows the driver to modify lighting instantly. Die-cast aluminum construction provides a lifetime rust-free protection. Powerful 55 watt Quartz Halogen XTRA bulb equals the intensity of a 100 watt bulb on the projector fog side and an 85 watt Quartz Halogen XTRA bulb performs similar to a 130 watt bulb on the driving side.
