Component Purpose and Function

The presented lamp socket harness is intended for installation in the rear of the vehicle, on the right side, within the trunk lid of the BMW F10. It is responsible for establishing a stable connection between the lamp and the electrical system, enabling the correct operation of the position light, brake light, and other functions specified for the particular lamp configuration.

This component is particularly useful when:

• the original harness has suffered mechanical damage (e.g., after a collision or lamp removal),
• there are issues with intermittent power supply to the trunk lid lamp,
• the socket needs replacement due to worn contacts or overheating.

Construction and Fit for BMW F10

The harness is designed as an OEM part dedicated to BMW, which translates to correct wire lengths, appropriate connector types, and compatibility with the factory trunk lid lamp. The lamp socket is ready for direct installation into the housing, and the connector on the vehicle's electrical system side allows for installation without modifying the main harness.

Its placement on the vehicle minimizes the risk of selection errors – the part is designated for the rear, right side, which simplifies identification when planning repairs or replacing lighting components.

Condition, Service Application, and Benefits of Installation

The offered component is used, allowing for an economical repair of the lighting system while maintaining original BMW specifications. In many cases, replacing only the harness with the socket is sufficient to restore the lamp's proper function without needing to purchase a complete lighting module.

The main benefits of using this harness include:

• factory fit for BMW F10 without the need for electrical system adaptation,
• the ability to quickly replace a damaged lamp socket,
• restoration of full functionality to the right rear tailgate light.

Application in Rear Lights and Brake Lights System

This component is part of the Rear Lights and Brake Lights system, responsible for the reliable power supply to the right tailgate lamp. A properly functioning harness with a socket minimizes the risk of dashboard lighting errors and issues with technical inspections resulting from faulty rear lights.
