Electrochromic function and driving comfort

The electrochromic interior mirror in the Ford Fiesta St automatically reduces the light intensity from vehicles behind, which limits the glare effect for the driver. A sensor system controls the dimming level of the glass, ensuring a clear view in various lighting conditions without the need for manual switching. This solution improves driver concentration during night driving, increases comfort on long journeys, and promotes safer observation of the situation behind the vehicle.

Carbon look appearance and interior integration

The carbon look finish gives the mirror a sporty appearance consistent with the character of the ST version, blending well with the dynamic styling of the cockpit. The applied texture and color scheme allow for aesthetic matching with other trim elements, without the "tacked-on" accessory effect. As a result, the mirror serves as a natural complement to the factory interior configuration, enhancing its visual appeal without interfering with the vehicle's structure.

Purpose and installation in the rear interior zone

The element is designed as an interior rear view mirror mounted in the rear part of the cabin, at the factory mounting point on the windshield. The OEM design enables correct adjustment of the viewing angle and stable seating, which translates into precise observation of the space behind the vehicle. Proper fitment to the bracket and windshield geometry facilitates installation and minimizes the risk of incorrect positioning or vibrations while driving.

Characteristics of the original Ford component

As a product of the Ford brand, the mirror maintains factory standards of build quality and compatibility with the vehicle's electrical system. Properly selected housing and mirror glass materials ensure stable optical parameters and durability under typical operating conditions. Manufacturer markings and assignment to a specific reference facilitate part identification in service catalogs and the selection of the correct component when replacing a damaged mirror.

Condition and application in service and upgrades

The offered item is used, which allows for an economical replacement of a damaged or worn mirror while maintaining the vehicle's original specifications. This type of component is suitable for both post-accident repairs and restoring full functionality of the automatic dimming system after a failure. Thanks to the preservation of factory geometry and mounts, the mirror can be used as a direct replacement in vehicles equipped with an electrochromic interior mirror.
