How Mirror Auto Dim Works
Mirror auto dim helps reduce glare from headlights behind you. It makes driving at night safer and more comfortable.
The mirror adjusts its brightness automatically. It uses special sensors and technology to detect light levels.
Light Sensors And Detection
Light sensors are placed on the mirror to detect brightness. They sense light from cars behind and from the front.
The sensors measure the intensity and direction of light. This helps the mirror know when to dim.
Automatic Brightness Adjustment
The mirror changes its brightness based on sensor input. It dims when bright lights are detected behind the car.
This adjustment reduces glare for the driver. The mirror returns to normal brightness in low light or daytime.
- Bright headlights trigger dimming
- Low light stops dimming
- Automatic changes happen quickly
Technology Behind Auto Dimming
The mirror uses electrochromic technology. This means it changes tint when electricity passes through.
Electrochromic material darkens the mirror glass. The amount of darkening depends on sensor signals.
- Light sensors send signals to a control unit
- Control unit adjusts electric current to the mirror
- Electric current changes the mirror’s tint level
