This component is particularly important in vehicles equipped with advanced lighting systems, where correct control of the LED diodes affects both driving comfort and the vehicle's visibility to other road users.

Vehicle placement and installation aspects

The module is designed for installation in the front area, on the left side of the vehicle, within the headlight assembly. Such precise vehicle placement facilitates the identification of the correct component when diagnosing lighting-related faults. Replacing the module usually involves removing the headlight or its parts; therefore, it is recommended that installation work be performed by a person with experience in servicing BMW lighting systems.

Product characteristics and condition

The offered module comes from disassembly and is a used component, which allows for an economical repair of the lighting system while maintaining the manufacturer's original specifications. A used component of this type is a good choice in situations where the factory module has suffered electronic or mechanical damage, and the user wants to restore full functionality of the LED cornering lights without interfering with the vehicle's installation.
