A variable focusing flashlight includes a barrel for housing a battery therein. A tail cap is mounted on one end of the barrel and has a spring for urging the battery towards the other end of the barrel. A lamp base retains a lamp adjacent the other end of the barrel. A head assembly is mounted on the other end of the barrel and has a planar lens and a parabolic reflector with an open tail end to receive the lamp. The lamp base includes a stationary receptacle mounted to the barrel, a first conductor mounted in the stationary receptacle for connecting one terminal of the lamp to a positive terminal of the battery, a second conductor mounted in the stationary receptacle for connecting another terminal of the lamp to a negative terminal of the battery via the barrel, and a movable receptacle mounted movably on the stationary receptacle to make or break connection between the first conductor and the battery. A conductive connector has an annular plate adjacent a bottom side of the stationary receptacle, an upwardly extending plate projecting from the annular plate and sandwiched between the stationary receptacle and the barrel, and a pointed protrusion extending from the upwardly extending plate to pierce an inner anodized coating of the barrel to connect electrically with the barrel.
