An improvement in a continuity tester is provided in a combination flashlight (or lantern)/electrical continuity tester having an insulated body and a (flashlight) bulb and batteries in series circuit. The improved continuity tester which is formed in the flashlight (or lantern) body, includes an entry site of a particular configuration into the interior of the body. The testing means includes a pair of electrically- conductive strips, each strip having a contact portion which is adjacent to the body entry site and which penetrates into the interior of the body. Each strip is also in electrical contact with one end of the series circuit. The shape of the entry site, i.e., the size, angle of convergence of the walls and the spacing of the channels or slits, is such as to act as guideways to guide terminals of the circuit element being tested into suitable electrical contacts. The electrical continuity of a fuse or light bulb is determined by the lighting of the bulb being tested and/or by the lighting of the lamp bulb of the flashlight.
