Audi's got a factory making pure LED headlights for its cars. Multiple LEDs make up two different arrays for regular & high-beam modes. The headlights will debut next year on the R8.

"At a current of 1 A, each LED array achieves a luminous flux of 600 lumen, Audi claims. For the future, the company plans to combine the LED technology with other innovative semiconductor-driven headlamp technologies such as swiveling headlights."
