The Audi matrix LED headlights are high beam headlights that are always activated. When oncoming vehicles are detected individual LEDs turn off so that the drivers are not blinded, while the remaining LEDs light up the rest of the area brightly. The matrix LEDs are currently available in Europe on the Audi A8, however they are not yet available here due to current headlight restrictions.
The laser lights are actually lasers behind an advanced lens used as high beam headlights, with LEDs providing the low beam function. These lights can project up to 1600 feet and are said to be brighter, sharper, and more efficient than LEDs. Audi will implement the lights in their R18s used in endurance racing, and will be the first manufacturer to put them into production.
