摘要：
A casing (61) has a transparent window plate (7) sealed therein. A reflector plate (12) is mounted on a diaphram (66) which forms a sealed chamber (72) with the base (64) of the casing. The casing (61) is mounted on a conventional mirror adjustment mechanism (80). A plurality of concial compression springs (73) urge the reflector plate (12) against the inside surface of the window plate (7) in the day position of the reflector plate (12). To move the reflector plate (12) for a day position to a night position, a pump (84) draws an optically dense light attenuating fluid from a reservoir (82) and pumps it into an annular chamber (78) and between the window plate (7) and reflector plate (12), to move the reflector plate (12) rearwards so that the fluid forms a masking layer between the reflector plate (12) and window plate (7). The masking layer extinguishes reflections from the reflector plate (12) in the night position. A solenoid valve (79) prevents return of the fluid to the reservoir (82) in the night position.
