Application and function in the vehicle

The presented BMW 3 Series E91N E91 LCI Rear Light Lamp In Trunk Lid Tailgate Right O/S is intended for installation in the facelifted BMW 3 Series E91 (E91N / E91 LCI) model on the right side of the vehicle's rear. This component contributes to the complete tailgate lighting assembly, responsible for clear signaling of maneuvers and maintaining the factory light geometry characteristic of BMW.

Thanks to its dedicated placement on the vehicle, installation is carried out at the mounting points provided by the manufacturer, which limits the risk of leaks, mechanical stress, and assembly errors. This is particularly important when replacing after a collision or repairing the tailgate.

Construction, fitment, and compatibility

The lamp has been designed as an original BMW part, which means maintaining the factory shape, lines, and lens division relative to the other rear lighting parts. As a result, after installation, you achieve a visually cohesive rear of the vehicle, without differences in shade or light geometry between individual segments.

Proper fitment to the tailgate facilitates:

• trouble-free seating in the original mounting hole,
• proper sealing at the contact point with the tailgate panel,
• correct routing of the electrical harness and connectors.

As a part from the Rear lights and brake lights group, the lamp works with the factory BMW electrical system, maintaining the light functions and lighting system logic intended by the manufacturer.

Condition, origin, and benefits of choosing a used part

The offered rear lamp is a used part, sourced from dismantling, which allows for an economical replacement while maintaining original BMW build quality. In practice, this means a real fit to the body and no need for installation modifications typical of cheaper replacements.

Choosing a used original part is particularly beneficial when you care about:

• maintaining the factory look of the vehicle's rear,
• maintaining compatibility with the other lamps,
• reducing repair costs while maintaining manufacturer standards.

Practical installation and operational tips

When replacing the rear lamp in the tailgate, it is worth paying attention to the condition of the seals, bulb sockets, and the electrical harness. A properly installed lamp should:

• adhere evenly to the tailgate panel,
• show no play or vibrations while driving,
• ensure uniform illumination of all light segments.

For full certainty of fitment, it is recommended to verify compatibility by the vehicle's VIN or consult a specialized BMW service, which minimizes the risk of selecting the wrong lamp variant for a specific equipment version.
