Audi has just released the information that the new 2014 A8 model is going to be equipped with brand new turn signal light. The latter will comprise of lighting elements that illuminate in a defined sequence. The aim behind this is to make it easier for others to perceive the driver's turning intentions.

The new turn signal lights will show the turning direction in an innovative way. In fact, the lights provide a visual signal, which allows a clearer and quicker perception, and even in long distances or in poor visibility.

To be more precise, each headlight contains 18 light-emitting diodes. They in turn are arranged in a strip that is subdivided into seven blocks. On the other hand, each tail light comprises of 24 LEDs in eight segments, which are used to dynamically indicate the turning direction.

How they work: during flashing, the blocks are sequentially activated at 20 millisecond intervals. The direction is from the inside to the outside and in the desired turning direction. All segments turn bright after 150 milliseconds. After another 250 milliseconds they illuminate with full intensity. Then, the turn signals go dark ahead of repeating the lighting sequence again.

Audi Matrix LED headlights are definitely a cutting-edge innovation. In each headlight, 25 light-emitting diodes develop a highly variable high-beam light. Audi A8 is equipped with an on-board camera as well. When it detects other vehicles ahead, the Audi Matrix LED headlights mask the relevant sections of the high-beam by dimming or shutting off individual diodes.

They also include navigation-based cornering lights which work in conjunction with the night vision assistant. The latter is a marker light which signals when pedestrians are in the vicinity in the dark. It also alerts the pedestrians.

The upgraded version of the Audi A8 with the new turn signals will be showcased at 2013 Frankfurt Motor Show in September.
