A power source is positioned within the housing for energizing a light source. A switch is connected to the power source and to the light source so as to energize the light source responsive to motion. The housing comprises a material which allows light from the light source to shine through so that it may be seen by a person observing the moving vehicle, and preferably includes a fluorescent material excited by an LED which emits ultraviolet light.
