Purpose and fitment

The presented lamp belongs to the Rear lights and brake lights group and was designed specifically for the Mercedes W212 model family. The placement on the vehicle is the rear left side, which allows for a precise fit to the factory mounting socket and electrical installation. As a result, this component can be used both for standard post-accident repairs and for replacing a worn or leaking lens.

Technical and functional parameters

The lamp works with the vehicle's factory electrical system, maintaining the original separation of position lights, brake lights, and turn signals (in accordance with the configuration provided for the given model). The construction based on the manufacturer's solutions ensures:

• correct light beam geometry,
• proper vehicle visibility from the rear,
• a consistent look with the right side of the body,
• stable mounting in factory mounting points.

Thanks to the preservation of the lamp's original form, the bodywork does not require additional modifications, and the installation process is orderly and predictable.

Product characteristics and condition

The offered lamp is a used component, which allows for economical repair while maintaining the original manufacturer's specifications. This type of component is particularly useful in situations where mechanical damage or a cracked lens has occurred, and the vehicle owner expects a part with factory appearance and compatibility. A used rear lighting component is also a sensible choice for repairs of older vehicles, where the cost-to-functionality ratio is key.

Application in the vehicle lighting system

The left rear lamp in the Mercedes W212 is responsible for signaling the vehicle's presence, braking, and changes in direction, which has a direct impact on road safety. Properly functioning rear lights and brake lights are essential for meeting regulatory requirements and passing periodic technical inspections. Replacing a damaged lamp with an original element from this series allows for the restoration of full system functionality without the need for installation modifications.

Benefits of choosing an original Mercedes lamp

By choosing this lamp, you gain:

• factory fit to the body and electrical installation,
• a consistent look for the rear of the vehicle,
• preservation of the lighting parameters provided by the manufacturer,
• a reasonable repair cost thanks to the use of a used part.

For owners planning further work on the lighting system, it is important that the product comes from the same design line as other rear lamp components, which facilitates later servicing and diagnostics.
