Automatic dimming function

The mirror uses an integrated dimming system that reacts to the intensity of light coming from behind the vehicle. As a result, the driver receives:

• reduction of glare from the lights of vehicles behind the car,
• a more stable image in the mirror during night driving,
• increased visual comfort during long journeys.

The automatic dimming works fully autonomously, without the need for manual adjustment, which promotes safer and calmer driving.

Purpose and fitment for Ford Focus Mk2

The presented mirror has been designed specifically for the Ford Focus Mk2 model, taking into account the interior geometry and ergonomics of the field of view. Its placement in the rear part of the cabin ensures an optimal angle for observing the road behind the vehicle, and the OEM design guarantees proper fitment with the factory mount.

Thanks to this, the element is a functional solution both for replacing a damaged mirror and for upgrading standard equipment to a version with automatic dimming.

Operational and installation characteristics

The mirror belongs to the Rear view mirrors group, which means its main task is to provide clear control of the situation behind the vehicle. The design intended for the rear area of the cabin allows for:

• maintaining the factory line of the Ford interior,
• correct positioning relative to the driver's seat,
• consistency with other cockpit equipment elements.

The item is used, which in practice means it comes from disassembly and may show signs of wear, but it remains intended for further service in the vehicle. It is a reasonable choice for drivers looking for an original component with a favorable price-to-functionality ratio.

Benefits of using an original Ford rear view mirror

• secure fitment to the factory mount and installation,
• preservation of the field of view intended by the manufacturer,
• comfortable operation in daily use.

For users who want to comprehensively take care of rear visibility, this is a solution that allows combining the functionality of automatic dimming with maintaining the original character of the Ford interior.
