Purpose and function in the lighting system

The presented trunk light bulb holder is a component of the vehicle's rear lighting system, mounted on the right side. It is responsible for the correct seating of the bulb and its contact with the electrical system, which allows for consistent rear lighting operation in accordance with the manufacturer's factory specifications. Thanks to its precise geometry and fitment to the lamp housing, the socket eliminates the risk of looseness, flickering light, or power supply issues.

Compatibility and fitment for BMW

As a part dedicated to the BMW 3 Series E91, the socket has been designed for the specific construction of the trunk lamp, ensuring proper fitment with the housing and wiring harness. Its original BMW origin means that it maintains the appropriate quality standards and compliance with the electrical parameters used in this model. This type of component is particularly useful when replacing a damaged holder, repairing the installation after a collision, or addressing issues with unstable rear lighting operation.

Benefits of using an original lamp holder

Using a dedicated bulb holder in the trunk lamp allows you to reduce the risk of faults resulting from the use of replacements with imprecise fitment. The main advantages include:

• a secure electrical connection, minimizing voltage drops and power supply interruptions to the bulb,
• stable bulb mounting in the housing, which reduces vibrations and extends its service life,
• preservation of the factory lamp geometry and correct light emission in the trunk area,
• easier diagnostics of potential lighting faults, thanks to compatibility with the original installation.

Choosing this solution is particularly beneficial when servicing a vehicle where maintaining consistency with factory specifications and predictable lighting system behavior is important.
