Abstract

Abstract An electro-optic rearview mirror system for a vehicle includes an interior mirror housing (10) containing an interior electro-optic mirror unit (18). At least one light sensor, and preferably a pair of light sensors (24, 26), is provided for sensing the ambient light level outside the vehicle. Control circuitry, which may be mounted on a PCB (36), is responsive to an output (34) from the at least one light sensor (24, 26) to establish a drive voltage for the electro-optic mirror unit (18). The PCB 36 is located outside the mirror housing (10) and mounted at the interior ceiling of the vehicle overhead and centrally between the driver and the front passenger, such as in a header (16) on the interior ceiling of the vehicle,
