Audi has released new details on the Matrix LED headlight that debuts on the Audi A8 facelift at the Frankfurt Motor Show next month.

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.

    In the USA, all 1965-66 Ford Thunderbirds were equipped with sequential turn signal indicators on the rear of the vehicle. Not such a new and innovative idea…

    I would call it an absolutely useless technology. What’s the difference it makes, when the lighting pattern is changed? It will only confuse other drivers, at least when seeing for the first time. To be frank, it reminds me about the pictures of Gods, which we saw in private buses long ago, having LEDs lighted like a running pattern.

    Hmm conceptually looks amazing …
    Would turn out to be a treat to watch in reality !!!

    I loved da concentric turn signals on da older Passat’s rear as well ! 😀

    I wonder why is this a news at all?
    Ford’s Mustang has had *growing* turn signals since 2011 !
