Xenon HID Headlight Ballast Module for BMW

The Xenon HID headlight ballast module, OEM cross-reference 63117182520, supplies the high-voltage ignition and steady power needed to run the factory xenon bulbs on 3 Series E90, E92, and E93 models.

Overview

This Xenon HID headlight ballast module is a replacement control unit for the factory xenon lighting system on the BMW 3 Series E90, E92, and E93.

Good To Know

Q: How do I know if my headlight problem is the ballast? A: If the bulb is new and still will not fire, or one side flickers while the other works, the ballast is the likely cause. Swapping ballasts side to side is a quick way to confirm.

Q: Can I install this without removing the headlight assembly? A: On most E90, E92, and E93 models the ballast is reachable from behind the headlight housing. Check your specific model year for access before starting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
