CIPA's auto dimming rearview mirror provides the perfect solution to annoying headlight glare at night. Mirror automatically dims to reduce glare from headlights reflecting in mirror. Sensors on the mirror indicate when bright lights are used and dim the mirror glass for comfort and safety. Installation is easy, requiring only a power wire to be run. Wedge mount mirrors are generally standard on vehicles manufactured in the United States, regardless of vehicle make. Wedge-style mirrors must be removed by loosening a small screw or clip, and pushing the mirror up towards the roof of the vehicle.
