  • Patent number: 6896390
    Abstract: A headlamp includes a housing securable to a human appendage. Within the housing a battery is located. Upon activation of a switch, the battery forms an electrical circuit with a light source located within the housing and directed to project a light beam therefrom. The housing is formed as an animate head having a mouth portion aperture defined by a hingeably secured jaw portion such that a light beam emanating from the light source projects through the aperture. The housing modifies the shape of the light beam and creates an inducement for a child-pedestrian to use the headlamp.

A adapted to press fit with the lower panel in simultaneous contact with the frame creates a flashlight that is readily opened to interchange and replace component parts. The upper panel also has an upper surface, a side and an aperture extending through the upper surface. The side of the upper surface has a notch receive a lever for detaching the upper panel. Transverse finger pressure on the aperture urges the LED leads into contact with the opposing surfaces of the battery thereby illuminating the LED.
