Some of the models at Trent Cadillac have high-tech features that offer assistance when driving around New Bern, NC. For example, certain vehicles come equipped with auto-dimming rearview mirrors, making it easier to see at night. How exactly do these auto-dimming mirrors work?
An auto-dimming rearview mirror has several components that you cannot see. It comes with sensors that can detect bright lights at night and has an electrochromic gel embedded between its two layers of glass.
When bright lights from a vehicle hit the mirror, the sensors send out electrical signals. These electrical signals are transmitted to the electrochromic gel, where they spark a reaction that causes the gel to darken. As a result, the images that are reflected by the mirror appear to be darker. The entire process happens quickly, and when the sensors stop detecting light, they stop sending their electrical signal. The gel becomes transparent once again.
