Purpose and function of the bulb holder

The presented socket is dedicated to the rear right side lamp in the Mercedes W203 and is responsible for secure bulb mounting and stable contact between the terminals and the vehicle’s electrical system. A properly selected socket eliminates the risk of light flickering, contact overheating, or intermittent power supply issues, which is important for both safety and compliance with traffic regulations.

This component is particularly important during post-collision repairs, replacement of a damaged lamp, or lighting system restoration, where it is necessary to maintain the original geometry and operating parameters of the side lamp.

Construction and compatibility with the lighting system

The socket has been designed as part of the LED lamps and lights system in the Mercedes, adhering to the manufacturer’s factory standards. The design includes:

• precise bulb guidance within the housing,
• proper contact arrangement for correct current flow,
• a shape matched to the housing of the rear right side lamp,
• compatibility with the vehicle’s original electrical wiring.

This solution facilitates installation and reduces the risk of errors during connection, which is especially important when working with used lighting components.

Vehicle placement and installation aspects

The socket is intended for installation in the rear right part of the body, within the side lamp. Clearly defined vehicle placement helps avoid mistakes when selecting parts and speeds up the service process. In practice, this means:

• easier identification of the correct mounting point,
• preservation of the factory wiring and connector layout,
• consistency with the original lamp and body construction.

The element is suitable both for replacing a single socket and for broader work related to repairing the vehicle’s rear lighting.

Characteristics of the used OEM component

The offered socket comes from dismantling and has the status of an original Mercedes part in used condition. In practice, this means maintaining the factory geometry, compatibility with the installation, and operating parameters specified by the manufacturer. For many users, this is a reasonable compromise between repair costs and maintaining the high quality of the lighting system.

A used OEM component also carries a lower risk of fitment issues compared to cheaper replacements, which is significant for precise electrical components such as bulb holders.
