A ballast is a crucial part of a fluorescent or HID lighting system. In a fluorescent lighting system, the ballast provides the voltage needed to start the lamp and regulates the electrical current of the light once it is lit. Without a ballast, the lamp would draw too much power, causing it to burn out quickly - sometimes even within a few minutes. The ballast prevents this from happening and ensures you get the benefits of the lamp's full lifetime.
This ballast fits for 05 - 08 A-udi A6 / S6, 05 - 08 A6 / A6 Avant / S6 / S6 Quattro, 04 - 08 A8 / S8, 03 - 05 B-M-W 5 series (E60), 02 - 04 B-M-W 7 series (E65 E66 E67 E68), 04 - 06 B-M-W X5 (E53), 03 - 07 B-M-W Z4 (E85 E86), 04 - 06 Pacifica, 02 - 06 F-ord Focus, 02 - 07 Jaguar S type, 02 - 07 Jaguar X type, 06 Land Rover Range Rover Sport, 06 - 08 Mercedes CLS class (W219), 03 - 06 Mercedes E class (W211), 02 - 08 Mercedes ML class (W164).

The ballast is to help your lamp start up quickly. When the lamp is turned on, the ballast provides a surge of higher voltage to the lamp. This helps establish an arc between two electrodes on the lamp, which is what causes HID bulbs to light up.After the electrode arc is established, the ballast reduces the voltage and regulates the electric current. This ensures the light produced is even and steady, without flickering or fading.
The ballast can act as DC to AC converter so that you can use the normal DC power source in the car to light the bulbs efficiently. The most common problem of HID Ballast failure is flickering, dipped beam not working or light failed, which may resulting from long term use. When have problems, you'd better replace it to avoid inconvenience to your driving. This ballast fits 2002 2003 2004 2005 2006 2007 2008 years.
