DailyTech: Audi R8 V10 Gets all LED Lighting
"Every light on the new Audi R8 V10 uses LEDs from interior lighting to the headlights. The new Audi R8 sports a much more powerful V10 engine that can push the vehicle to close to 200 MPH. Not only is the vehicle one of the fastest Audi's ever produced, it is the one of the first cars to bear the Audi marquee that will exclusively use power efficient LED lighting everywhere.
LEDs are used for the turn indicators, headlights, running lights and all interior lighting. The headlights used in the new R8 are the first in a completely new generation of LED only headlamps. A typical xenon headlight puts out about 80 lumens of light per watt. Early LED headlamps that Audi used on vehicles and concepts put out a mere 18 lumens per watt. The new LEDs used in the R8 are able to put out 100 lumens per watt, making them more efficient than xenon headlights for the first time ever.
One of the most interesting aspects of the new LED lighting system used on the R8 is that the light beam from the headlamps can be digitally controlled and changed as the environment changes. The lights can not only offer an indefinite lifespan, but the beam can be brighter when needed and then self-dim by changing the light beam when the vehicle gets close to other vehicles on the road. This helps prevent the possibility of blinding oncoming drivers."
