FUNCTION - A HID Ballast is a device required by a xenon headlight (bus also for fluorescent lamps) to regulate voltage and current supplied to the lamp during start. It also provides enough voltage and current throughout operation. Without a ballast, the lamp would consume too much energy, which would cause it to burn out quickly - sometimes even within minutes. The ballast prevents this from happening and ensures you get the benefits of the lamp's full lifetime. Direct replacement for your original one; Easy installation. 1 Year Warranty.
