How do your auto-dimming mirrors work?


We here at ALL STAR DODGE CHRYSLER JEEP RAM understand the importance of being an informed driver so that you can make the most of your vehicle. Features such as an auto-dimming rearview mirror can help to make night driving safer, but how does it work?

Auto-dimming mirrors make use of sensors that detect light from other vehicle's headlights. These sensors can either be a camera or a photodetector. A microprocessor controls these sensors and is designed to send an electrical charge to the electrochromic gel.

The electromagnetic gel lies in between the two layers of glass that make up the rearview mirror. When electricity is applied to the gel, it darkens the gel and causes it to darken. This helps to reduce the amount of light that is reflected by the mirror. At night this can be invaluable to avoid getting blinded at night from bright headlights driving behind you.
