Purpose and function in the lighting system

The presented bulb socket is a component from the Rear lights and brake lights category, responsible for the mechanical and electrical operation of bulbs in the vehicle's rear left lamp. It is mounted in the rear section of the body on the driver's side, where it is responsible for the proper operation of position lights, brake lights, turn signals, and other functions provided in the given lamp configuration.

A properly selected bulb socket minimizes the risk of looseness, contact overheating, and unstable electrical contact, which translates into safe and predictable rear lighting performance in daily operation.

Construction and fitment for Mercedes W204 / C204

The holder has been designed specifically for the Mercedes C-Class W204 / C204 platform, which means it is perfectly matched to the lamp geometry, mounting points, and electrical connectors. The design provides precise bulb guidance in the socket, as well as appropriate arrangement of current paths to maintain the correct sequence and function of individual lights.

As a result, this component can be used as a replacement for the original holder in the event of mechanical damage, burnt contacts, or electrical conductivity issues in the existing lamp module.

Condition, service application, and installation

The offered bulb socket is a dismantled, used part, making it an attractive service solution for users looking for an economical lighting system repair while maintaining compliance with the factory design. This type of part is suitable both for typical replacement of a damaged holder and for rebuilding a lamp after a rear collision.

Installation involves mechanically seating the holder in the lamp housing and connecting the factory electrical harness connector. With the correct selection of the component for the specific body version and lamp, it is possible to maintain plug-and-play functionality without the need for harness modifications or interference with the vehicle's electronics.

Benefits of using the original bulb socket

• Ensuring the correct position of bulbs in the lamp, which affects the readability and visibility of light signals.
