A vehicular interior rearview mirror system includes an interior rearview mirror assembly having a mirror head adjustably mounted at a mounting structure. The mirror head includes a mirror casing and an electro-optic variable reflectance mirror reflective element. A glare light sensor senses glare light emanating from headlights of another vehicle rearward of the equipped vehicle. An ambient light sensor senses ambient light at the vehicle. The ambient light sensor comprises part of a rain sensing device disposed at an in-cabin side of a windshield of the vehicle. Mirror control circuitry is operable to adjust dimming of the mirror reflective element responsive to an output from the glare light sensor and an output from the ambient light sensor. Responsive to the output from the glare light sensor and the output from the ambient light sensor, the mirror control circuitry controls dimming of the mirror reflective element.

Interior rearview mirror system with ambient light detection

A vehicular interior rearview mirror assembly includes a mirror head having a mirror casing and an electro-optic mirror reflective element. A printed circuit board is disposed in the mirror head and includes (i) a light sensor, (ii) an indicator LED and (iii) an electronic switch. A multi-function light pipe is disposed at the mirror head with (i) a first end at the light sensor, the indicator LED and the electronic switch, and (ii) a second end at a perimeter region of the mirror head so as to be viewable and accessible by the driver of the vehicle. The light sensor senses light from rearward of the vehicle via the light pipe. Light emitted by the indicator LED, when energized, is viewable by the driver via the light pipe. The light pipe actuates the electronic switch responsive to a user actuation at the second end of the light pipe.
