Purpose and vehicle placement

The presented lamp belongs to the Rear lights and brake lights category and is intended for installation in the rear, right part of the vehicle.

Technical and functional characteristics

The tail lamp in this model is responsible for generating light signals necessary for safe road travel – in particular the position light and brake light. The design was prepared by the vehicle manufacturer, which translates into:

• precise fit to the electrical installation,
• adequate visibility of light signals for other road users,
• preservation of factory optical parameters.

Thanks to this, the rear lighting system maintains its functionality and meets safety and signal readability requirements on the road.

Brand, origin, and condition of the component

The lamp comes from the Mercedes brand, which means it is a component designed for a specific vehicle platform, rather than a universal replacement. The used condition of the part (used) makes it a cost-effective solution while maintaining the original design and mounting compatibility.

The element is suitable for users who want to restore full efficiency of the rear lighting after a collision, mechanical damage, or operational wear, while maintaining consistency with other body components.

Selection and vehicle compatibility

To correctly select this lamp for a specific vehicle, it is worth paying attention to manufacturer markings, OEM part numbers, and available interchangeable numbers, which allow for verifying compatibility with a given body version and model year. Proper selection guarantees:

• trouble-free installation in factory mounting points,
• correct connection to the existing electrical harness,
• preservation of the original stylistic line of the vehicle's rear section.

Additionally, the SKU identifier facilitates unambiguous product assignment in the store system, and the OEM part number and interchangeable numbers help in technical compatibility verification.

Expansion and modernization of Mercedes rear lighting

If you are planning a comprehensive repair or modernization of the rear lighting zone in your Mercedes and need other elements from the same group, such as additional tail lamps, brake light modules, or complete lighting assemblies, check the available parts in the Mercedes rear lights and brake lights category.

Practical installation and operational tips

When replacing the tail lamp, it is worth paying attention to the condition of electrical connectors and seals at the point of contact with the body. A correctly installed element:

• prevents moisture from entering the lamp,
• protects the electrical installation from corrosion,
• maintains stable mounting during vehicle operation.

To maintain uniform color and intensity of lighting, it is recommended to periodically check all light points in the rear of the vehicle, which allows for quickly detecting any differences in the operation of individual lamps.
