Audi says other drivers can quickly and easily perceive the intention of the A8's driver when he's indicating a direction change.

The integrated turn signal lights is an assembly made of 18 light-emitting diodes arranged in a strip that is subdivided into seven blocks. Each taillight is made of 24 LEDs in eight segments, which indicate the turning direction.

Each block is activated sequentially at 20 millisecond intervals, from the inside to outwards in the desired turning direction. After 150 milliseconds, all segments are bright; for another 250 milliseconds they illuminate with full intensity. Afterwards, the blinkers go dark before repeating the lighting sequence.
