Purpose and function in the vehicle

The design includes factory mounting points and an electrical connector compatible with the vehicle's installation, which facilitates assembly and reduces the risk of leaks or looseness.

This solution allows for:

• maintaining the original styling line of the mirror,
• proper guidance of the light beam towards the front and side of the vehicle,
• stable seating in the housing, without the need for modifications.

• appropriate light parameters matched to the mirror construction,
• maintaining a uniform appearance with other body elements.

Condition and service application

The offered wing mirror turn signal is a used part, making it a sensible choice for post-accident repairs, replacement after mechanical damage, or light module failure. This allows for an economical repair while maintaining factory fitment to the wing mirror and proper signaling operation.
