CHECK OUT HOW AUTO-DIMMING REARVIEW MIRRORS WORK

Have you ever looked at a component of your vehicle and thought, how does this work? At Burritt Motors, we like to help Oswego, NY drivers understand the features of their automobiles. Auto-dimming rearview mirrors were designed to reduce glare and are a standard feature with most vehicles, but how do they work? Let’s find out. Auto-dimming rearview mirrors reduce glare with a process called electrochromism. Ambient light sensors, which are typically semiconductors or cameras, work with a microprocessor to detect glare from trailing vehicle’s headlights. The sensors and microprocessor send a charge to an electrochromic gel. The charge causes the gel to go through an oxidation-reduction process. This will cause the material in the gel to lose transparency and become darker. The gel sits between the two layers of glass that make up the mirror, and when the gel darkens, it will restrict the amount of light that hits the driver’s face.
