ABSTRACT:
Vehicle parking assist apparatus includes a hollow mounting base, an elongated signaling device, such as an upright pole having a signal light mounted thereto, supported on the base for pivotal movement from a normal upright non-signaling position to a tilted signaling position upon being contacted by an advancing vehicle, and an electrical circuit connected to the signal light of the elongated signaling device and capable of being switched from an open circuit condition to a closed circuit condition for electrically actuating the signal light to provide a visible alerting signal for a driver of the advancing vehicle. A coupling device supports the pole upright on the base and also couples the signal light to the electrical circuit. The coupling device is capable of retaining the electrical circuit in an open circuit condition so long as the signaling device is disposed in the upright non-signaling position. The coupling device is further capable of switching the electrical circuit to the closed circuit condition in response to the elongated signaling device being contacted and tilted by the advancing vehicle to the tilted signaling position.
