Purpose and function in the vehicle
This rearview mirror is a BMW rearview mirror and is mounted inside the vehicle, in the rear cabin, on the windshield. Its purpose is to provide a clear view of the area behind the car while reducing glare from the headlights of vehicles behind.
Auto Dip EC (electrochromatic dimming) technology automatically adjusts the mirror's tint to current lighting conditions. This eliminates the need for the driver to manually switch to night mode, ensuring stable and predictable visibility.
Auto Dip EC technology and LED backlight
The mirror is equipped with an electrochromic layer that responds to the difference in light intensity between the front and rear of the vehicle. When the sensor detects strong light from behind, the mirror gradually darkens, reducing glare and improving the driver's visual comfort.
Built-in LED lighting provides even, energy-efficient illumination of selected interior zones. LEDs are characterized by stable light color, low energy consumption, and long lifespan, which is particularly beneficial in everyday car use.
- Automatic dimming to reduce glare from vehicles behind.
- Stable, bright interior lighting thanks to LED technology.
- Stylistic consistency with the factory equipment of the BMW 3 Series.
