    Patent number: 5915330
    Abstract: A temporary automobile marker is provided with a hollow base cone and a tower cone attached to the top of the base cone. The tower cone is co-centric with the base cone but has a smaller diameter in order to form two surfaces that help reflect light in a discontinuous fashion in order to make the marker more visible. A magnet is encased within the hollow base cone. The bottom edge of the base cone is covered with a pad so that the base cone and the encased magnet will not harm the surface of the vehicle to which the marker is attached. A method for employing the marker is also provided.
