1. A rearview mirror assembly for a vehicle comprising:

  • an electrochromic mirror including;

    front and rear spaced elements, each having front and rear surfaces and being sealably bonded together in a spaced-apart relationship to define a chamber therebetween,a layer of transparent conductive material disposed on said rear surface of said front element,a reflector/electrode including at least one layer of a conductive reflector/electrode material disposed on said front surface of said rear element,an electrochromic reversibly variable transmittance medium contained in said chamber in contact with said transparent conductive material and said reflector/electrode, anda sensor area disposed within said reflector/electrode, said sensor area having regions containing reflector/electrode and regions substantially devoid of reflector/electrode; and

    a sensor mounted behind said sensor area of said electrochromic mirror for sensing light transmitted through said electrochromic mirror, wherein said reflector/electrode material is effective to reflect light through said electrochromic medium and said front element when the light reaches said reflector/electrode after passing through said front element and said electrochromic medium.
