ABSTRACT:
The subject invention comprises a light-reflective device comprising an article made of light-reflecting material to which is attached fastening means rotatably mounted thereto. Because of the moveable features of the fastening means of the subject invention, the article may be attached to varying objects in varying positions with respect thereto. For example, the reflective device may be worn by a jogger on his or her clothing. In addition, the device may be easily attached to a sneaker or a sock or a bicycle or a baby carriage and the like. Furthermore, because the reflective surface moves in varying positions relative to the fastening means, as the object to which it is attached moves (for example, a jogger), light, impacting upon the surface of the light-reflective device, is reflected in a pulsating manner thereby rendering the object more visible to an oncoming observer.
