"When blasting down the Mulsanne straight at more than 200 mph in total darkness and at two in the morning, headlights that can clearly illuminate the road ahead are crucial. That&amp;#039;s why Audi is upping the technological ante again for 2014 with laser-based lighting on the redesigned R18 e-tron Le Mans prototype.  When the original R18 debuted in 2011, Audi incorporated a full LED-based headlamp array on the front to help its drivers see the slower cars it was reeling in. The massive LEDs remain on the new car, but they are being augmented on the new car with laser lamps similar to those that will be available later this year on the new BMW i8.  The lasers themselves don&amp;#039;t actually provide the light directly but shine on yellow phosphorous crystal lenses. The laser beam excites the phosphorous, which causes it to emit a white light that shines off a reflector and onto the road. The result is expected to be a brighter and more uniform field of light in front of the car, even at greater distances. "^^<http://www.w3.org/2001/XMLSchema#string>
