ABSTRACT:
A modular flashlight is formed from three parts which are screwed together--a battery housing, a switch housing, and a head. An O-ring at each screw connection provides a substantially watertight seal. A bulb is mounted in the switch housing and a reflector is mounted in the head. Rotation of the head relative to the switch housing varies the focus of the light reflected by the reflector. The head can be removed from the switch housing so that the bulb can provide candle illumination.
