New Audi A8 gets innovative turn signal light

(August 15, 2013) The new Audi A8 will come with a the turn signal light consisting of lighting elements that illuminate in a defined sequence making it easier for others to perceive the driver’s turning intentions, even under difficult conditions.

Audi says the new signals have the potential to significantly enhance traffic safety. That's because the lights provide a visual signal that can be clearly and quickly perceived, even at long distances and in poor visibility.


Also each of the enhanced Audi A8 headlights contain 18 light-emitting diodes arranged in a strip that is subdivided into seven blocks. Each tail light contains 24 LEDs in eight segments, which are used to dynamically indicate the turning direction. During flashing, the blocks are sequentially activated at 20 millisecond intervals, from the inside outwards in the desired turning direction. After 150 milliseconds, all
segments are bright; for another 250 milliseconds they illuminate with full intensity. Afterwards, the turn signals go dark before repeating the lighting sequence.

Considering their capabilities, the Audi Matrix LED headlights can be regarded as a cutting-edge innovation. In each headlight, 25 light-emitting diodes generate a highly variable high-beam light. When the on-board camera detects other vehicles ahead, the Audi Matrix LED headlights mask the relevant sections of the high-beam by dimming or shutting off individual diodes. Very bright illumination is preserved in the remaining zones.

The Audi Matrix LED headlights also feature navigation-based cornering lights and, in cooperation with the night vision assistant, a marker light that warns the driver of pedestrians in the dark and which also alerts the pedestrians.

Audi will be presenting the upgraded A8 in September the Frankfurt Motor Show.
