Purpose and vehicle placement

Thanks to the precise fit to the W177 series body, the element maintains the car's stylistic line, and installation does not require interference with the body structure or additional modifications.

Technical and functional characteristics

The inner tailgate lamp works with the other rear lighting elements, responsible for clearly signaling vehicle maneuvers. The design intended for the specific Mercedes model enables:

• stable mounting in factory mounting points,
• correct light beam guidance along the vehicle axis,
• maintenance of uniform light color and intensity in the rear set.

The original origin from the Mercedes brand means compliance with the manufacturer's requirements regarding safety, optics geometry, and compatibility with the vehicle's electrical installation.

Condition of the element and benefits of using a used part

The offered lamp is a used element, which allows for an economical repair of the lighting system while maintaining factory build quality. Compared to low-budget replacements, the original used part provides:

• better fit with the tailgate panel,
• preservation of the original light line,
• compatibility with factory installation connectors.

For many users, this is a reasonable compromise between repair cost and maintaining a high standard of vehicle finish.

Identification and vehicle fitment

Precise matching of the part to a specific body version is facilitated by the SKU marking and the assigned OEM part number. Additionally, interchangeable numbers are available, which allow verifying compatibility with other references used by the manufacturer. Information about the placement on the vehicle eliminates the risk of confusion between the left and right side or an outer and inner element.

Application in service and lighting modernization

Replacing the inner tailgate lamp is recommended in case of mechanical damage, leaks, problems with the operation of light segments, or differences in light color between the sides of the vehicle. Using an original component from the Rear lights and stop lights group helps maintain compliance with traffic regulations and aesthetic consistency of the rear bodywork.
