Abstract: A vehicle parking aid and signaling device having a housing section which encloses an electrical circuit connected with an electric switch for opening and closing the circuit and the circuit operatively connected with a signaling light or buzzer. The switch is actuated by having a movable lever arm maintained in direct engagement with an expandable elastic bulb which is operatively connected with a deformable tubular member filled with a fluid and which causes the elastic bulb to expand momentarily and effect closing of the electrical circuit containing the signaling light or buzzer when a wheel of a vehicle moves over and compresses the deformable tubular member; thereby indicating when the vehicle has reached a predetermined position.

Abstract: A parking guide and signaling device for cars and trucks to assist the driver parking a vehicle in a designated parking area comprising a housing section having a window in the front wall thereof which is closed by a pane of translucent sheet material through which indicia can be seen clearly when the indicia are illuminated from the rear surface of the pane by an electric light with electrical means within the housing for illuminating said pane and the housing section having pivotally mounted thereon an actuating lever biased so that the electric means is normally "off" but when the vehicle moves into a designated parking area the electrical means is turned "on" and an intense beam of light illuminates the inner surface of said pane.

Abstract: A parking guide and signaling device for cars and trucks to assist the driver parking a vehicle safely in a designated parking area comprising a housing section with a window therein which is closed by a pane of transparent sheet material through which indicia can be seen only when the indicia is placed in contact with the rear surface of the pane and with the housing having pivotally mounted therein an actuating lever biased so that the upper end of the actuating arm is normally spaced rearwardly of the pane and having secured to the upper end of the arm a plate with warning indicia on the front surface thereof adapted to be moved into contact with said pane and the lower end of the actuating arm extending forwardly below the housing section and adapted to be moved pivotally rearwardly by a vehicle as it moves into a designated parking area and bringing the warning indicia place into contact with said pane.
