Description
Genuine BMW Xenon Headlight Control Unit
Restore the operation of your BMW’s compatible xenon headlight system with this Genuine BMW High Intensity Discharge (HID) Headlight Control Unit.
The HID headlight control unit, also commonly referred to as a ballast or igniter, regulates the voltage and electrical current required to operate xenon headlights. It provides the initial high-voltage ignition needed to illuminate the HID bulb and helps maintain the electrical supply required for consistent lighting.
Heat, moisture and electrical stress can contribute to control unit failure over time. A faulty unit may cause headlight warnings, failure to illuminate, intermittent operation or uneven brightness.
Common Failure Symptoms
- Headlight not turning on: The HID bulb fails to ignite even though other vehicle lights operate.
- Flickering or intermittent lighting: The headlight switches on and off while driving.
- Dim or uneven brightness: One headlight produces less light than the other despite having a functioning bulb.
