US Patent 6896389 Headmounted light

Headmounted lights provide a hands-free source of illumination without tethering the user to external equipment. A power source, on/off switch, and light source are enclosed by a housing that is removably attached to a belt by a pouch. A fiber-optic cable transmits light from the light source to a headband-mounted lens assembly. The lens assembly can be aimed via an adjustable mount that connects a reflector and lens to the front of the headband. The size of the headband can be adjusted by a friction locking mechanism attached to its rear. The headband has both a horizontal portion and a vertical portion. Headband protrusions extend from the vertical portion. Clips removably attach the fiber-optic cable to the headband and the belt.
