Purpose and Function in the Vehicle

The right rear tail light bulb holder in the Mercedes A-Class W176 generation is responsible for securely seating the bulbs and correctly connecting them to the vehicle's electrical system. The component is designed for installation in the right rear part of the body, thus maintaining the correct light beam geometry and compliance with the original lamp design.

As part of the LED Lamps and Lights group, the holder works with the rear lamp, ensuring proper contact conductivity, connection stability, and resistance to typical operational loads such as vibrations or temperature changes.

Construction and Technical Fit

The original design of the bulb holder is prepared for direct installation into the right rear lamp without the need for modifications or adaptations. The arrangement of the bulb sockets, the shape of the housing, and the mounting points are consistent with the original Mercedes design, which facilitates installation and minimizes the risk of leaks or looseness.

Key functional features of the bulb holder:

• dedicated placement in the right rear lamp,
• factory fit for the Mercedes W176 electrical system,
• stable bulb guidance and mounting,
• maintenance of correct lighting function distribution (position lights, brake lights, turn signals – according to the specific lamp configuration).

Benefits of Using an Original Bulb Holder

Using an original bulb holder in the right rear lamp helps avoid problems typical of aftermarket replacements, such as imprecise fit or unstable contacts. This allows you to:

• reduce the risk of intermittent light failures caused by poor electrical contact,
• maintain compliance with the original lighting system parameters,
• facilitate potential electrical system diagnostics, as all connections correspond to the manufacturer's schematics.

A used OEM part is also an economical solution while maintaining the proper quality and fit standard, which is particularly important for components responsible for vehicle safety and visibility.

Condition, Verification, and Service Application

The bulb holder is a used part obtained from disassembly, offered for cost-effective restoration of the right rear lamp's functionality. This type of component is often chosen for:

• repairs after collisions involving the right rear part of the body,
• mechanical or thermal damage inside the lamp,
• problems with intermittent rear light operation due to worn contacts.

Thanks to its original geometry and connectors, the installation of the bulb holder is straightforward for a service center or an experienced mechanic, with the entire operation involving simply transferring the part and connecting the factory wiring harness.
