Patent Images
1. A hand-held flashlight comprising:
- a flashlight head with a transparent lens and sidewalls defining a first cavity;
a flashlight body with at least one longitudinal wall and a second cavity;
housing interconnecting means for interconnecting said body and head to form a common enclosure;
a primary electrical system disposed in said enclosure for generating a primary beam through said lens;
a backup electrical system disposed in said enclosure and separate from said primary electrical system for generating a backup light beam through said lens, said backup electrical system comprising a backup battery disposed in said first cavity; and
activation means for selectively activating said primary and backup systems.

Abstract
A hand-held flashlight has a housing for two independent electrical systems: a primary system and a backup system. Each of the systems includes a light source, a power source and a switching device for selectively connecting a power source to a corresponding light source. The backup system uses high performance components to insure that the flashlight is operational for long time periods. The backup system is actuated only after the the primary system has failed. An indicator announces when the backup system is in operation.

19. A flashlight comprising:
-
a housing consisting of a head, and a body and means for connecting said head and said body in a matting relationship; a first electrical system completely disposed in said head, said first electrical system remaining intact when the body and head are separated for generating a first light beam; and a second electrical system substantially disposed in said body for generating a second light beam emitted through said head.
