You're not wrong if you think that headlights are getting brighter and brighter. Although headlights are a wonderful safety feature, they can be a real annoyance when reflected in your rearview mirror. Luckily, there’s a clever solution that will help to relieve the problem.
Auto-dimming rearview mirrors use modern technology to solve the age-old problem. Spread between the two panes of glass in the rearview mirror is a substance called electrochromic gel. When this gel is exposed to electricity, it darkens immediately. If the vehicle behind you has its lights in your mirror, a sensor registers that fact and sends electricity into the gel. The mirror absorbs the light rather than reflecting it into your eyes. The mirror returns the gel to its normal state as soon as the light source is gone.
