If you spend a lot of time driving at night, you know the frustration of constantly flipping your rearview mirror whenever a vehicle is behind you. Auto-dimming rearview mirrors can eliminate this frustration. Auto-dimming rearview mirrors not only make it easier to see at night but also make for safer nighttime driving. Through the use of photosensors, the mirrors are able to detect the amount of light in front of and behind your vehicle.
This detection is possible from the mirror element and electronic system in the auto-dimming rearview mirrors. It uses a layer of electrolytes that consists of identical crystals arranged by the application of voltage. This determines how much light is reflected. The mirror automatically becomes darker when the amount of light from behind is more than the light from behind. Although it may sound complicated, this helpful technology is easier than you'd think.
