Driving around at night can be dangerous, especially if you have to contend with the glare of other vehicles' headlights. This glare greatly reduces your visibility and reaction time, which is why many of the vehicles sold at Land Rover Tacoma in Fife, WA are equipped with auto-dimming rearview mirrors.
Auto-dimming rearview mirrors first became largely available in the 1980s, and the basic technology behind them hasn't changed much over the years. An auto-dimming mirror contains sensors that detect the glare from other vehicles' headlights. When the glare becomes too bright, the sensors send an electrical charge through a layer of electrochromic gel within the mirror. This gel darkens with this charge, which causes the mirror itself to darken enough to reduce the glare from the headlights. This improves your night visibility and ensures you can reach your destination safely.
