The module has been designed specifically for selected Mercedes models, ensuring it maintains proper operating parameters and fits the safety and comfort systems.

Key advantages include:

• factory electrical fitment for Mercedes installations,
• stable cooperation with other control units in the vehicle,
• the ability to restore full functionality of the lighting system without modifying wiring harnesses.

Product characteristics and condition

The offered module comes from a Mercedes vehicle and is a used component, which in practice means an attractive cost-to-functionality ratio while maintaining original build quality. This type of solution is particularly beneficial for repairs where both technical compatibility and service budget optimization are important.

Thanks to the preservation of the factory housing design and connectors, installation is similar to replacing a component with a new one, without the need for installation modifications or the use of additional adapters.

Selection and compatibility of the control unit

When selecting a headlight control unit for a specific vehicle, it is crucial to verify compatibility with the body model, production year, and equipment configuration. The product has an assigned OEM part number and interchangeable numbers, which facilitates unambiguous identification in service catalogs and parts selection systems, without the risk of ordering errors.

It is recommended that the installation and any necessary adaptation of the module be performed by a workshop equipped with appropriate diagnostic software, which will allow for the correct integration of the control unit into the vehicle's existing electronic network.

Expanding the lighting system and related components
