ABSTRACT:
A flashlight includes a barrel portion for enclosing and retaining batteries and comprising an end for accepting a movable bulb enclosure. The moveable bulb enclosure engages the end of the barrel so that the bulb enclosure is axially movable along the barrel portion. A bulb holder is provided at the second end for removably holding a bulb such that the bulb is relatively stationary during axial movement of the bulb enclosure. A stop is provided on the end of the barrel portion for preventing complete removal of the movable bulb enclosure from the barrel portion.
