A pivotal support means is provided mechanically coupled to the mounting bracket for substantially supporting the weight of the truck mirror. An electric motor is mounted on the mounting bracket for moving the mirror, and a gearbox is mechanically coupled to the motor and adapted to be mechanically coupled to the truck mirror so as to adjust the plane in which the mirror lies wherein, in use, an operator can adjust the angle of the mirror by activating the electric motor.
