A bidirectional flashlight with long-ranged and short-ranged illumination having a metal tube with a headlight, a tail light, a power supply and a two-way switch wherein the tail light includes an insulating mounting seat within a tail cover with a surrounding lens. A plurality of light-emitting diodes directed to the outside is installed in the mounting seat. Moreover, A negative conductive strip and a positive annular conductive strip lean against an internal wall of the mounting seat and are electrically connected to the negative and the positive terminal of the light-emitting diodes, respectively. A negative connection piece is interposed between the negative conductive strip and the tail cover. A battery positioning reed is attached to a bottom end of the battery chamber while a positive terminal contact piece with a front and a rear contact piece is disposed against the inner wall of the battery chamber. An power supply spring is interposed between a positive terminal of the battery and the power supply connection strip. Besides, a front positive terminal spring is interposed between the tail light connection strip and the front contact piece while a rear positive terminal spring is interposed between the rear contact piece and the positive conductive strip. Furthermore, a negative terminal spring is interposed between the positioning reed and the negative conductive strip.
