Auto-Dimming Rearview Mirrors: What They Are, How They Work, and Why You Need One

Having bright headlights show up in your rearview mirror while traveling on dark Sand Creek, WI streets could leave you unable to see the road ahead for nearly two seconds. Although this doesn't seem like long, you can easily cover quite a bit of distance. Worse still, with temporarily impaired vision, you won't be able to take evasive action if needed. At Gilberts of Sand Creek, we're showcasing the benefits of auto-dimming rearview mirrors by explaining how they work.

Microprocessors Register Bright Headlights

Auto-dimming rearview mirrors are equipped with tiny microprocessors. These units detect bright lights and instantly transmit electric charges. These charges are received by an autochromic gel that's sandwiched between two panes. This gel responds to electric signals by changing its color. As it darkens, the images reflected in auto-dimming mirrors darken as well.

Drive Confidently in All Conditions

With an auto-dimming rearview mirror, you can drive confidently in foggy conditions and on dark, poorly lit roads. This device will ensure that you're never temporarily blinded by the bright headlamps of following vehicles.
