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.
