Application and Function in the BMW F45 Active Tourer

The presented bulb holder is a component of the LED Lamps and Lights system in the tailgate of the BMW F45 Active Tourer. It is responsible for the mechanical stabilization of the bulb and for safely supplying power to the rear lamp, which translates into a clear position light, brake light, or turn signal – depending on the specific lamp configuration in a given vehicle.

Its placement on the vehicle covers the rear part of the body on the left or right side, allowing the same type of holder to be used in both tailgate lamps. This solution simplifies servicing and reduces the number of part variants used in the vehicle.

Construction and Technical Properties

The bulb holder has been designed as an OEM BMW installation component, with appropriately shaped contact sockets and mounting guides. This ensures:

• stable seating of the bulb in the tailgate rear lamp,
• precise guidance of electrical contacts,
• correct positioning relative to the reflector and lamp lens.

Thanks to its factory fit, the holder works with the vehicle's original wiring harness, minimizing the risk of looseness, contact overheating, or intermittent power interruptions. This is particularly important in modern lighting systems where control units monitor the correct operation of the lamps.

Condition, Origin, and Benefits of Using OEM Parts

This component comes from the group of original BMW components and is classified as a used part. This means that its construction, mounting geometry, and manufacturing standard meet the vehicle manufacturer's factory requirements. In practice, this translates to:

• secure fit to the tailgate rear lamp without modifications,
• preservation of the factory lighting characteristics,
• reduced risk of errors in light control systems.

Using an original bulb holder is particularly beneficial for repairs after a collision, replacement of a damaged lamp, or restoring the full functionality of the lighting system in a BMW F45 Active Tourer.

Practical Installation and Operational Tips

When installing the bulb holder in the tailgate, pay attention to its correct seating in the lamp socket and the cleanliness of the electrical contacts. It is good practice to check the condition of the lamp seals and power cables to avoid moisture ingress and corrosion of the connections. After installation, it is recommended to check the correct operation of all rear lighting functions – position lights, brake lights, and turn signals – via the onboard computer and visually.

If you are planning a comprehensive repair or upgrade of the tailgate lighting area in your BMW and need other components from the same group, such as additional housings, lamp modules, or other bulb holders, check the available parts in the BMW LED Lamps and Lights category.
