1. A flashlight comprising:
- a barrel inside which a conductive inner surface is formed and batteries are retained;
a head integrally affixed to an outer periphery of a first end of the barrel, wherein a face cap is screwed to a forward end of the head and a reflector is retained inside the face cap;
a light emitting module attached at the first end of the barrel and inside the head, wherein the light emitting module has two electrodes respectively and electrically contacted with an anode of the batteries and the conductive inner surface of the barrel; and
a tail cap made up of conductive material, wherein a base is integrally formed with and extends upward from the tail cap, a cavity is defined in the base to retain a spring and a conductor that is to contact with a cathode of the batteries, and an electrical isolating ring to screw to a second end of the barrel surrounding the base.

Abstract
A flashlight has a barrel formed with a conductive inner surface to retain batteries therein, a head attached to one end of the barrel and having a light emitting module retained inside the head, wherein two electrodes of the light emitting module are respectively and electrically contacted with one electrode of the batteries and the conductive inner surface of the barrel. A tail cap is provided to enclose the other end of the barrel, wherein the screwing rotation between the tail cap and the barrel determines whether an electrical loop is closed or open so as to control the activation of the flashlight.
