Audi shows off A4’s optional matrix LED headlights [video]

Audi has released yet another promotional clip for the new A4 compact premium sedan , this time showing off the optional matrix LED headlights.

As standard, the A4 (B9) comes with Xenon Plus headlights but at an additional cost you can get LED or these matrix LED clusters which in low beam resemble an eye and have eleven light diodes requiring just 20 watts of power. As for the full beam, this is generated by twelve LEDs with three reflectors and work depending on the data provided by the camera mounted on the interior mirror. There’s a control unit which switches them on and off individually as necessary and can automatically dim the diodes in one of the 64 stages available.

Audi says this method enables the matrix LED headlights to distribute light in several million possible combinations which all provide optimal lighting without disturbing traffic participants. The headlight’s cornering function works with the optional MMI Navigation plus system and is activated even before the driver steers as the headlights “learn” from the sat-nav there’s a corner up ahead.

Lastly, the matrix LED headlights come with dynamic turn signals which have several light diodes activated sequentially from inside and out in the direction of the turn.
