The flashlight includes a barrel with an internal cylindrical sleeve containing two dry cell batteries disposed in series. A lamp bulb holder assembly includes conductors for making contact between electrodes of bulb and the cylindrical sleeve in the barrel and an electrode of the battery, repsectively. A tail cap and spring member encloses one end of the barrel and, through the remote end of the sleeve, at the tail cap, provides an electrical contact to the other electrode of the batteries. A head assembly includes a reflector, a lens, and a face cap, and is rotatably mounted to the barrel such that the lamp bulb extends through a hole in the centre of the reflector within the lens. |
