The HID or Xenon Ballast in your BMW or Cadillac vehicle is responsible for supplying power to your headlight’s bulb. Overtime your HID Ballast can fail resulting in a headlight that flickers or does not turn on at all. This AA Ignition HID Xenon Ballast is a direct replacement for the ballast on your BMW or Cadillac vehicle. Every ballast is designed to connect directly to your vehicle and requires NO programming or coding.
Each of your vehicle’s headlights has its own ballast. These ballasts are commonly mounted either on the back or on the bottom of the headlight. While the HID Xenon Ballasts do commonly fail so can your factory headlight bulb. Please see our procedure below to determine if your factory HID Xenon Ballast has failed or if you simply need to replace your headlight bulb.
Please make sure that the part you are replacing looks exactly like the one pictured with the same part numbers.
The bulb out warning light on your instrument cluster can signal that there is a problem with your headlights. While sometimes a bad headlight bulb can be to blame, it can also be a bad HID ballast. Follow our instructions below to confirm if your HID ballast is bad.
