A visibility aid for improving the visibility of the wearer of the aid or the object to which the aid is attached, said aid including at least one light source mounted for electrical connection to a power source and an electrical switch. The light source and electrical connections are provided within a reflective band with an outer and inner layer and the outer layer is formed of retroreflective material and forms the outer face of the visibility aid. The aid is improved over conventional devices by the use of substantially flat light sources which are displaced from the retroreflective material and in substantially the same plane as the electrical connections. The electrical connections are also provided on a flexible material to enable the visibility aid to be flexible in use. <IMAGE> |
