  • Patent number: 7743724
    Abstract: The invention is an ultrasonic whistle that screws onto the valve stem of a vehicle tire. A variety of alternative embodiments utilize a housing that screws onto the valve stem with variations as to how air travels across the whistle. As the vehicle's tires rotate, wind passes across the whistle, which in turn produces sound that is audible to animals and in turn alerts animals of the oncoming traffic.
