A mirror actuator for trucks whereby the mirror may be adjusted from a position adjacent the seat of the driver to provide maximum visibility from the right hand mirror. A lever is positioned in the truck adjacent the seat of the driver so that the lever may be actuated by the driver while the driver remains in the driving position. The lever in turn controls a cable which is secured to the exterior right hand mirror assembly so that actuation of the lever will cause a corresponding pivotal movement of the right hand exterior mirror about its vertical center line.
