The offered module comes from the line of original solutions used in Mercedes vehicles, promoting consistency with the factory electrical architecture. The product has a dedicated OEM part number and associated replacement numbers, allowing for precise verification with service documentation or the manufacturer's catalog.

Additionally, key identification parameters such as SKU, part number, and a list of reference numbers are provided on the product card, facilitating the matching of the module to the specific headlight configuration and equipment version.

Vehicle Placement and Installation Aspects

The ballast is designed to operate on the right and left sides of the vehicle, allowing for flexible use in various headlight variants for Mercedes W117 models. This solution reduces the number of different references needed in service and speeds up the replacement process.

The module should be installed in the location designated by the headlight manufacturer, with appropriate protection against moisture and overheating. Proper seating within the lamp housing and correct connection of electrical connectors are crucial for stable lighting system operation and to avoid errors in the vehicle's diagnostic system.

Product Characteristics and Condition

The offered component is a used part, allowing for economical repair of the lighting system while maintaining the original manufacturer's specifications. This type of solution is particularly beneficial for electronically advanced modules where compatibility with factory software and operating parameters is important.

The ballast, as a component from the Ballasts and Igniters for Lamps category, is intended for users who expect technically correct headlight operation without the need for modifications to the electrical system or the use of universal solutions.

How to Select the Right Module and What to Look For

When selecting a module, it is advisable to verify:

• the compatibility of the OEM part number with the vehicle's documentation,
• the list of replacement numbers assigned to the specific headlight model,
• its intended use for a specific vehicle side (right/left) according to the lamp configuration,
• consistency with the equipment version and type of lighting used.

This minimizes the risk of installation errors and communication problems between the module and other vehicle controllers.
