Zusammenfassung:	A vehicle mirror assembly comprising a reflective element ( 21 ) for reflecting incident light (I), the reflective element ( 21 ) having a viewable side, a means ( 20 ) for varying the intensity of light (I) reflected from the viewable side, a photo-electrical power cell ( 35 ) for powering the means ( 20 ) for varying the intensity of reflected light (I) and a control means ( 40 ) for controlling the means ( 20 ) for varying the intensity of reflected light (I) in response to ambient light (A) conditions, wherein, in use, the intensity of the light (I) reflected from the viewable side is reduced in low ambient light (A) conditions. In other embodiments a power storage means is defined, for providing intermittent power to power the means ( 20 ) for varying the intensity of light (I) reflected, the power being supplied by the photo-electric power cell ( 35 ).
