Abstract: A mirror system for improving a motorist's field of vision, and comprising at least one mirror having a convex reflecting surface, and a housing capable of being mounted beneath an exterior surface of a vehicle for accommodating therein the at least one mirror when not in use. A mechanism within the housing elevates the at least one mirror out of the housing through an opening in the exterior surface of the vehicle and rotates the at least one mirror after its elevation through the opening into a line of sight of the motorist thus allowing a cross-section of the opening to have a smaller area than a cross-section of the at least one mirror. After use, the mechanism retracts the mirror(s) into the housing, preferably automatically under control of a controller.
