Purpose and function in the lighting system

The presented socket with wiring is designed for installation in the trunk lid on the right side of BMW F10/F11 series models, in the area of Tail lights and brake lights. It is responsible for a secure connection between the lamp and the vehicle's electrical system, enabling the correct operation of the position light, brake light, and other lighting functions provided in this lamp module.

Its placement in the rear right part of the vehicle minimizes the risk of installation errors – the design of the socket and plugs is matched to the specific lamp, which facilitates service and reduces the time required for repairs.

Construction, connectors, and compatibility

The item is a complete lamp socket with a section of wiring, prepared for operation in the factory BMW electrical system. The connectors used are designed for:

• a secure electrical contact under conditions of vibration and temperature changes,
• resistance to typical current loads for tail lights,
• easy disconnection during lamp service or trunk lid removal.

Thanks to maintaining the original geometry of the connectors and wires, the socket works with the factory lamp and installation without the need for modifications, which is particularly important for repairs in vehicles equipped with advanced lighting control systems.

Condition, origin, and benefits of using a used part

The offered item comes from the group of original BMW parts in used condition. This type of component is a good choice when you want to maintain factory build quality while optimizing repair costs. A used socket with wiring allows you to restore the full functionality of the rear lighting without interfering with the original installation.

In practice, this means:

• maintaining compliance with factory electrical parameters,
• no need for adapting universal connectors,
• consistency with the vehicle's diagnostic systems.

Safety, diagnostics, and service application

A functional lamp socket with wiring has a direct impact on the reliability of tail lights and brake lights. Damaged contacts, melted connectors, or broken wires can cause dashboard errors, unstable lighting operation, or a complete lack of light, which reduces safety levels and may result in a negative technical inspection result.

Replacing the socket is recommended especially when:

• there are intermittent losses of the tail light or brake light on the right side,
• signs of overheating or corrosion are visible on the connectors,
• diagnostics show lamp circuit errors in the trunk lid.

Using an original socket with wiring allows you to restore the correct electrical parameters of the circuit and reduces the risk of recurring faults in this area.
