Allowing you to reduce the number of lights used, or to run a DOT Compliant 4 head light system. Providing the driver unsurpassed visibility and safety. Multiple LEDS for Improved Visibility: High beams on the VX Series LED headlights utilize the same IRIS Reflector technology that's used in the popular Light Cannon series from Vision X. These long-range reflectors help push the light from the high beam LEDs to surprising distances, where as the reflector for the low beam LED was engineered to produce a wide beam pattern to cover the entire roadway. Each beam is precisely positioned to keep light out of the eyes of traffic, ensuring they are unimpaired from the light. Two elliptical beam LEDs in head light are aimed to fill in the roadway right in front and to the sides of the vehicle. Increasing safety, and comfort while driving.
