What type of rearview mirror dims when there is a car behind you with the headlights on?

• A. Electrochromic Mirror
• B. Auto-Dimming Mirror
• C. Standard Glass Mirror
• D. Smart Dim Mirror

Answer: (A)

When glare from headlights behind you is detected, the mirror automatically darkens using electrochromic tech. An electrochromic rearview mirror has a special coating that changes tint when an electric signal is applied, reducing reflectivity and blocking the bright light from behind you. This automatic dimming is what keeps your eyes comfortable and helps you see the road better.

A standard glass mirror doesn’t dim at all, and while you may hear terms like auto-dimming or smart dim, the specific technology behind the dimming is electrochromic. That underlying mechanism is why this type is the correct answer.
