ABSTRACT:
A flashlight includes a tube with a head provided at a front end. A light reflector is disposed in a front end of the head. A casing is force-fitted within the front end of the tube. A switch is fixed on the casing. An end cap, a spring and an end plate are disposed in an insulator which is received in a retainer. A light bulb is retained in the retainer. The switcher controls an electrical circuit of the flashlight. The light bulb is stable relative to the tube so that a rotation of the head relative to the tube makes the light reflector move relative to the light bulb.
