Purpose and Function in the Lighting System

The presented bulb holder is a component from the Rear Lights and Brake Lights group, responsible for the mechanical and electrical handling of bulbs in the rear lamp. Mounted in the rear area of the vehicle, it acts as an intermediate module between the electrical harness and the lamp itself, enabling the proper operation of position lights, brake lights, or turn signals – depending on the lamp configuration in a specific car model.

Construction and Mounting Parameters

The socket has been specifically designed for the rear lamp construction in Mercedes W164 models, maintaining factory mounting points and contact routing. Thanks to this:

• it fits the dedicated lamp housing without modifications,
• it ensures correct bulb positioning relative to reflectors and the lens,
• it maintains stable electrical contacts under conditions of vibration and temperature changes.

Its placement at the rear of the vehicle body facilitates servicing – access to the socket is typically from the trunk side or the lamp service cavity, following the manufacturer's factory procedure.

Service Application and Benefits of Replacement

Replacing just the bulb holder is a beneficial solution in situations where lighting problems occur, such as intermittent light failures, overheated contacts, or mechanical damage to the holders. Using an original Mercedes part allows you to:

• restore proper rear light function without replacing the entire lamp assembly,
• maintain compatibility with the vehicle's factory electrical system,
• minimize the risk of errors in lighting control systems.

A used product offers a reasonable compromise between repair cost and maintaining original technical specifications, especially for vehicles used daily.

Compatibility and Part Identification

The Mercedes W164 rear lamp bulb socket is an original component, which facilitates its identification in service catalogs and matching to specific body versions. In practice, this means:

• easier selection of the correct variant for your specific car model,
• consistency with factory wiring harnesses and connectors,
• no need for installation adaptations or the use of adapters.

Before purchasing, it is advisable to compare the shape and contact arrangement with the currently installed element to confirm full mounting compatibility.
