The Audi Matrix LED technology combines LED light sources with precision optics for highly adaptive light distribution.
If vehicles are detected by the camera system, the system selectively masks just the area of the detected vehicle while all other segments of the high beam remain active. Switching between the respective light distributions and regulation while oncoming traffic is passing are visible in the headlights as dynamic operations and adapted for the driver’s lighting convenience.

In addition to the Matrix LED function, the headlights include the following functions: visually upgraded daytime running lights, dipped beam, high beam, position light, dynamic indicator, turning light (supplements lateral illumination when turning off), all-weather light (to reduce the risk of the driver being dazzled when visibility is poor), manoeuvring light (illumination of the front side manoeuvring area when reversing), motorway light (extended light range at high speeds) and automatic-dynamic headlight range control.

The Matrix LED headlight also performs the synthetic cornering light function. Using data from the navigation system (in conjunction with the MMI navigation plus) for assistance, the cornering light function starts responding shortly before the steering wheel is turned.
 
The headlights include a dynamic indicator: The segments of a strip of LEDs are illuminated in turn within milliseconds, thus creating the appearance when indicating that the light is moving in the direction in which the vehicle is turning.
