Abstract: There is disclosed a vehicle indicating mechanism, in the form of a parking guide, for gauging the back clearance of an automobile or similar vehicle. The parking guide includes a hollow, translucent guide rod, which is movable responsive to a motor within a control box, from a substantially horizontal position, adjacent to the back bumper of the vehicle, to a substantially vertical position, extending upwardly from the corner of the bumper. The guide rod is illuminated by a light within the control box when the rod is in the vertical position, thereby also enabling the rod to be viewed by the driver and used as a guide for parking the automobile, at night.
