The new Audi A4 recently introduced in Europe is the ninth generation of Audi's popular mid-sized model. The A4's lighting system offers a blend of technology and aesthetics. HELLA-designed features include rear combination lamps with innovative LED technology, a lighting-control unit for actuating headlamps and additional small exterior lamps, as well as a roof module and rear lamp in the interior.

Osram has developed and produced the LEDriving Xenarc headlight, its first full retrofit headlight. The front lighting on the Audi A4 is equipped with a combination of xenon and LED technologies. Osram is the only manufacturer so far to offer the option of a legal upgrade to xenon light without the need for costly reconstruction of the front of the vehicle.
