Abstract
A mirror for a motor vehicle comprises reflective means having a primary surface and a secondary surface, the reflective means being arranged to reflect light which is incident on its secondary surface. A layer on its primary surface adapted to change from a transparent state to a reflective state in response to application of a control signal so as to change the field of view or the intensity of the reflected image. In another form of the invention, the reflective means is arranged, when in a first state, to reflect light from a reflective surface having a first configuration adapted to provide a first field of view. The reflective means can be changed to a second state in which light is reflected from a reflective surface having a second configuration adapted to provide a second field of view differing from said first field of view.
