Modern technology upgrades in vehicles often blend safety with driver convenience. Auto-dimming rear-view mirrors are the perfect example of that principle in action. While bright headlights used to threaten your nighttime vision, your rearview mirror can now make that problem a thing of the past.
A bit of chemical wizardry is responsible for your mirror’s quick reflexes. Between the two panes of glass that make up your mirror is a layer of electrochromic gel. This gel reacts to a pulse of electricity by instantly darkening in color. When a special sensor in your rearview mirror’s housing detects a bright light, it sends an electric charge into the gel. As the gel instantly darkens, it absorbs the excess light coming from the traffic behind you, keeping the bright reflection out of your eyes.
Once the light source is gone, the electric pulse ends, and your mirror reflects the scene behind you just as it ordinarily would. Test drive a new Subaru today at Northtown Subaru in Amherst, NY.
