Purpose and function of the module

The presented module controls the headlight range in the vertical axis, coordinating the movement of the adjustment mechanism on the right and left sides of the vehicle. This allows the lighting system to react to changes in vehicle load, maintaining the correct beam angle and improving road visibility. A properly functioning headlight range module reduces the risk of blinding other drivers and supports stable headlight operation in various driving conditions.

Compatibility and installation

The module is designed for use in Mercedes W205 series vehicles equipped with electronic headlight range control. The placement on the vehicle covers both the right and left sides, allowing for flexible use of the component depending on the lamp configuration in a given vehicle. The controller's design allows for installation in place of the factory module, while maintaining the original electrical system architecture.

Technical characteristics and condition

This is an original component from the Ballasts and igniters for lamps group, designed to work with the factory Mercedes W205 lighting system. The module has a dedicated OEM part number and assigned replacement numbers, which facilitates verification of compatibility with a specific vehicle configuration in the manufacturer's catalogs or service systems. The product is marked as used, which represents a favorable compromise between repair costs and maintaining the original system specifications.

Benefits of using an original module

Using a factory headlight range control module in a Mercedes W205 allows you to maintain the consistency of the vehicle's electronics and reduce the risk of communication errors in the controller network. Original architecture and software promote seamless cooperation with leveling sensors and other lighting system components. This is a particularly beneficial solution for users who expect stable headlight performance and want to avoid problems typical of low-quality replacements.

Technical support and additional information

Before purchasing, it is worth comparing the OEM part number and replacement numbers with the data in the vehicle documentation or service system to confirm full compatibility of the module with a specific equipment version.
