Purpose and Technical Function

The presented bulb holder is dedicated for installation in the rear of the vehicle, within the combination lamp area. It is responsible for:

• mechanically holding the bulbs in their correct working position,
• ensuring a stable electrical contact with the vehicle's wiring system,
• proper functioning of the position lights, brake lights, and other functions assigned to the rear lamp.

Thanks to its precise geometry and appropriate contact layout, the socket integrates seamlessly with the factory wiring harness, simplifying installation and reducing the risk of errors.

Compatibility with Mercedes Models

The socket has been designed for selected Mercedes upper and mid-range models that utilize specific rear combination lamps. The holder's construction meets the manufacturer's requirements regarding the arrangement of light points and the routing of electrical circuits.

Selecting the correct bulb holder for a specific vehicle ensures installation consistency, prevents lighting error messages, and guarantees uniform illumination of all lamp segments.

Performance Characteristics and Installation

This component is intended for installation in the rear lamp, replacing the factory holder. The design features:

• precise bulb guidance within the socket,
• appropriately spaced contacts for individual circuits,
• the possibility of removal for servicing or bulb replacement.

The holder is a disassembled part from a vehicle, meaning it originates from the original installation and has been verified in real-world operating conditions. This is a practical solution for users looking to restore full lighting functionality without altering the factory wiring harness.

Application in Tail Light and Brake Light Systems

Functional tail lights and brake lights are crucial for safety and regulatory compliance. A properly selected bulb socket minimizes the risk of:

• circuit interruptions and flickering lights,
• contact overheating during prolonged operation,
• malfunctioning of individual lamp functions.

Replacing the holder is particularly recommended in cases of signs of overheating, contact corrosion, or intermittent lighting issues where simply replacing the bulbs does not resolve the problem.
