1. A rearview mirror assembly for a vehicle, said rearview mirror assembly comprising:

  • a mirror reflective element comprising at least one glass substrate and a mirror reflector established at a surface of said at least one glass substrate;

    a touch sensor device disposed behind at least a portion of said mirror reflective element and operable to sense the presence of a person'"'"'s finger at a touch zone of said mirror reflective element proximate to said touch sensor device;

    a backlighting device disposed behind said touch sensor device and operable to backlight at least a portion of said touch sensor device;

    wherein said touch sensor device comprises a generally light transmissive touch sensor substrate having a patterned electrically conductive trace established at said touch sensor substrate, and wherein said patterned electrically conductive trace is established at said touch sensor substrate in a pattern that allows light emanating from said backlighting device to pass through said patterned electrically conductive zone of said touch sensor substrate;

    an icon disposed generally at said patterned electrically conductive trace at said touch sensor substrate; and

    wherein, when said backlighting device is activated, light emanating from said backlighting device passes through said patterned electrically conductive trace said touch sensor substrate and illuminates said icon so that said icon is viewable through said mirror reflective element by a driver of the vehicle when said rearview mirror assembly is normally mounted at the vehicle.
