Purpose and Function of the Component

The presented bulb holder is dedicated to the rear left side of the vehicle body, where it is responsible for the correct positioning and connection of light sources within the lamp. As an original Mercedes part, it maintains the proper socket geometry and stable current paths, which translates to predictable operation of the parking lights, brake lights, or turn signals.

Thanks to its precise fit to the lamp housing, installation is orderly, without the need for wiring modifications or interference with the vehicle's electrical harness. This solution is particularly beneficial for professional collision repairs and for replacing a damaged bulb panel.

Construction and Technical Features

The rear lamp bulb holder for the Mercedes OE class ensures compliance with the vehicle's factory specifications. The panel's construction is designed to:

• hold bulbs in a stable position, minimizing the risk of looseness and flickering lights,
• ensure a secure electrical contact in the sockets, reducing voltage drops and contact overheating,
• facilitate service bulb replacement without specialized tools,
• maintain compatibility with the rear lamp's factory electrical harness.

This solution allows for maintaining the consistency of the lighting system, which is important for both driving safety and proper interaction with the vehicle's control systems.

Condition, Fitment, and Service Application

The component is offered as a used part, which in practice means a favorable compromise between repair cost and maintaining original manufacturing quality. For workshops and individual users, this means the possibility of restoring full functionality to the rear lamp while preserving the factory installation standard.

The holder is intended for installation on the rear left side of the vehicle, so when selecting it, pay attention to the compatibility of the body side and the B W245 body version. A correctly chosen bulb panel reduces the risk of installation errors, lamp leaks, or lighting system diagnostic problems.

Benefits of Using an Original Bulb Holder

Using a factory bulb holder in the Mercedes-Benz B W245 offers a number of practical benefits:

• Replication of Factory Installation – the panel is structurally matched to the original lamp, facilitating installation and removal.
• Stable Lighting Operation – proper contact and socket guidance reduces the risk of circuit interruptions and lighting errors.
• Seamless Integration with the System – no need for harness modifications or adapter use.
• Reasonable Repair Cost – a used OEM part allows for reduced service costs while maintaining high manufacturing quality.
