CIPAs line of Day/Night mirrors are the perfect replacement for your factory installed mirror. This 12 inch mirror attaches to the windshield on a swivel mount, and can be tilted to reduce the brightness and glare of headlights shining directly at eye level. The front and rear internal faces of the Day/Night mirror glass are not parallel to one another, allowing a manual tab adjustment to switch between day and night positions. In the day position, the front face is slanted and the reflective back-side provides a strong reflection. When in the night position, its reflective rear face is slanted out of line of the driver’s sight. Since the non-reflective front allows the majority of the light to pass through, only a tiny amount of light is reflected into the driver’s eyes. This means an increase in both safety and comfort at a fraction of dealer costs. Also available in an 8 inch design (part number 31000), 10 inch design (part number 32000), and a design featuring map lights (part number 36000). Fits OEM mounting on all cars, trucks and vans. Mirror mounting adhesive not included. Bracket is included. FMVSS approved. Expand your horizons.
