ABSTRACT:
A multi-section multi-purpose hand light incorporates a shade casing, a head cover, a refraction hood, red filter lens and a body comprised of a number of cylindrical sections. The red filter lens can be releasably fastened to the retractable refraction hood. The light being emitted thereby will be a focused red light beam surrounded by an aureole of white light. This hand light may serve as a striking signal for help where needed to facilitate search and rescue efforts by a tracing team. The intensity of illumination can be increased by an increased number of the cylindrical sections. Spare bulbs or replacement parts can be stored in the bottom section of the body. The hand light also serves as a regular hand light by removing the red filter lens from the hood and coupling it to the bottom section of the hand light.
