Gentex pioneered the electrochromic automatic-dimming mirror, which detects and eliminates dangerous rearview mirror glare, making nighttime safer for drivers around the world.

Today, Gentex mirrors are the optimal space in the vehicle for the placement of a broad array of electronic technology and are lower in cost than designing electronics into the vehicle interior. Locating informational displays in the mirror also affords increased safety, requiring the driver to simply glance at the mirror while remaining focused on the road.
