Auto-dimming rearview mirrors work by first sensing that there is too much light in the cabin and activating an electrical current. From there, the electrical current will flow through a gel in the mirror itself that will help gradually absorb the excess light.
When that extra light is neutralized, the dimming feature will shut itself off without any need to do anything yourself. At Land Rover Cape Fear in Wilmington, NC, we want you to know why this feature is better than simply moving the mirror to get the light out of your eyes.
First, you won't need to take your eyes off the road, which could increase your risk for an accident. In addition, you may forget to put the mirror back where it belongs, which could make it harder to see behind you when traveling in poorly lit areas of town.
