Abstract: An item of apparel is disclosed that can be worn on various parts of the body such as the ankle, the arm, the wrist or the like comprising a fabric sleeve having Velcro at its ends so that it can be formed into a loop embracing the user's limb. A series of light-emitting diodes are mounted on the sleeve and connected to a battery powered circuit having a mercury switch so that the diodes are illuminated depending upon the position of the user's limb. Each diode is mounted in a reflector that magnifies the diode's illumination.
