Purpose and function in the lighting system

The presented socket with wiring is a component from the Rear lights and brake lights group, responsible for the electrical connection between the right lamp and the vehicle's wiring. Its placement in the rear zone, on the passenger side, allows for the operation of position, brake, or turn signal light functions in accordance with the specific lamp configuration.

This component is particularly useful for:

• repairing a damaged connector or burnt contacts in the rear lamp,
• resolving intermittent lighting issues on the rear right side,
• bodywork and paint repairs where the original wiring harness has been compromised.

Connector and wiring construction

The rear right lamp socket is equipped with a dedicated plug connector, matched to the design of the lamp used in the Mercedes V177. The integrated wiring harness allows for direct connection to the vehicle's electrical system, without the need for custom connections or soldering.

This solution:

• reduces the risk of installation errors in the lighting circuit,
• ensures repeatable, stable electrical contacts,
• facilitates diagnostics in the event of future faults.

Benefits of using an original Mercedes component

The original socket with wiring for the rear right lamp has been designed specifically for the V177 body geometry and the electrical parameters of the factory lighting system. As a result, it fits factory mounts and connectors, and installation is limited to replacing the component and plugging it into the existing blocks.

The main advantages of using an original component include:

• maintaining compatibility with the factory electrical installation,
• no need for wiring modifications or the use of adapters,
• consistency with the vehicle's onboard system diagnostics.

Condition, service application, and installation

The item is sourced from disassembly, making it an attractive solution for post-accident repairs, electrical system service, or replacing a damaged lamp connector. The used OEM component allows for maintaining consistency with the rest of the installation while reducing costs compared to new parts.

In practice, installation involves:

• removing the right rear lamp and disconnecting the old socket,
• routing the wiring through the factory guides,
• connecting the plug to the lamp and the vehicle's electrical system.
