Abstract: A retractable mirror assembly for a tractor trailer includes a base component having a pair of arms and a motorized hydraulic cylinder mounted on the upper surface thereof. The arms are pivotally attached at a lower end to the base component and at an upper end to a mirror. The hydraulic cylinder includes an upper distal end that is pivotally attached to an outer edge of the mirror. A control panel within the vehicle passenger compartment activates the motor allowing a driver to automatically extend and retract the mirror between an operable and inoperable position.
