BMW Headlight Driver Module Halogen Light - Genuine BMW 63117304906

Product Information

A headlight control module (sometimes called a headlamp control unit or lighting control module) is an electronic unit that manages and regulates a vehicle’s headlight functions. It communicates with onboard sensors, switches, and the vehicle’s ECU to control operations such as:

• Turning headlights on/off automatically based on ambient light conditions.
• Operating daytime running lights (DRLs).
• Adjusting beam levels (auto-leveling systems).
• Managing adaptive or dynamic headlight systems (e.g., cornering lights, matrix LEDs).

It ensures proper illumination for safety while optimizing power consumption and compliance with regulations.

• Headlights Not Functioning Properly – One or both headlights may fail to turn on, flicker, or remain stuck in high/low beam.
• Warning Lights or Error Messages – Dashboard warnings (e.g., “headlamp malfunction”) appear due to faulty communication with the ECU.
• Loss of Advanced Functions – Automatic headlights, adaptive beam control, or daytime running lights stop working as intended.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
