Abstract
The invention provides an automatic rearview mirror system (10) for a vehicle comprising a reflective element (22) actuatable between at least two different reflective conditions. The system includes a forward light sensor (11) to detect light forward of the vehicle and a rear light sensor (12) to detect light rearward of the mirror. A control circuit means (14,16) is coupled to the reflective element (22), the forward light sensor (11) and the rear light sensor (12). The control circuit causes the reflective element to assume a reflective state dependent upon the output of the forward and rear light sensors. The control circuit includes means for modifying the output of the forward light sensor (11) to cause a reduction in the sensitivity of the mirror.
