ABSTRACT:
An embodiment of the present invention provides a mirror subassembly having a dimmable dichroic liquid crystal mirror on one side and a conventional mirror on the opposite side, and a mirror housing which permits mounting of the mirror to the housing in either a first or second positions. In normal operation, the mirror subassembly is mounted to the housing in the first position with the dimmable mirror as the viewing surface. The dimmable mirror can be caused to operate a high reflectance state or low reflectance state by electronic control. Upon power loss, which causes the dichroic liquid crystal mirror to revert to a low reflectance state, the mirror subassembly can be manually mechanically mounted to the housing in the second position with the conventional mirror surface of the mirror subassembly as the viewing surface.
