The ballast is a key component in the starting system of the factory-installed xenon system. It acts like a transformer that converts the voltage from your battery into a suitable amount of power to ignite the xenon bulbs. HID ballasts also serve as converters from DC to AC. Since your car's headlights cannot operate on direct current (DC) supplied by the battery, they take in direct current and convert it to alternating current (AC).
The igniter is suitable for the following vehicles:
