CIPA s line of Day/Night mirrors are the perfect replacement for your factory installed mirror. This CIPA 33000 12 Day/Night Rearview 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 backside 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.
