Abstract: A flashlight is provided that can be switched between a white light mode wherein it produces white light and a color mode wherein it produces primarily light of a particular color such as red, which can be easily operated with the same hand that holds the flashlight. A hood (34 of FIG. 2) of material that passes only red light is mounted on the lens (40) of the flashlight, and the periphery of the lens is mounted on a select member (46) that can be moved forwardly and rearwardly with respect to the rest of the flashlight. When the select member is moved to its rearward position, the hood intercepts substantially all of the light passing between a lamp (32) and the reflector (36) of the flashlight, so that primarily red light is produced by the flashlight. When the select member is moved to a forward position (46A), the hood lies forward of most of the light rays passing between the lamp and the reflector, so the flashlight produces primarily white light.

Abstract: A bulb and switch assembly for a flashlight including a bulb having first and second leads, a fixed switch body having first and second holes in one end, a first terminal in the first hole contacting the first lead, a conductor in the second hole contacting the second lead, and means for storing a spare bulb on the switch body.

Abstract: An adjustable focus flashlight comprising three units: a head, a replaceable switch unit, and a battery unit. The replaceable switch unit includes a switch assembly having two holes in one end for bulb leads, and a holder near that end for storing a spare bulb. The replaceable switch unit also includes a cylindrical member around the switch assembly, which is externally threaded, at the end near the holes, to engage the internal threads of the head, and adjust the focus. A flexible sleeve fits around the outer surface of the cylindrical member, the sleeve having a circular protrusion formed in the end thereof, to frictionally engage part of the head, and maintain a selected focus adjustment.
