Abstract:
Methods and apparatuses are disclosed for providing illumination for physical restraint devices, such as handcuffs. In some embodiments, the handcuffs may include a luminescent material. The luminescent material used may be the type that utilizes energy from a light source to provide light when the light source is removed, such as phosphorus. Alternately, the luminous material may be “self-luminous” and not utilize an external light source to provide light. Exemplary self-luminous materials may include tritium.
