Genuine OEM Mercedes-Benz Headlight Ballast Control Module designed for vehicles equipped with LED / Xenon headlight systems. This control unit regulates the electrical power supplied to the headlamp, allowing the light to ignite correctly and maintain stable brightness.

The ballast module is mounted on the headlight housing and communicates with the vehicle’s lighting control system to ensure proper headlamp operation and safety. A faulty ballast may cause flickering headlights, dim lighting, or complete headlight failure.

The OEM part number A2129008224 is used in several Mercedes models and should match the original module to ensure proper compatibility. It is commonly installed on vehicles with Intelligent Light System (ILS) LED headlights.
