A portable electric warning light comprises an elongated electrically conducting housing to which an end cap is connected at one end to provide an on/off switch function and to which a gas discharge flash tube is connected at the other end for emitting, through both end and side walls of a cover connected to the housing, bright flashes of light in response to the operation of batteries and an electronic circuit contained within the housing. The batteries are rechargeable, which can be accomplished in a particular implementation wherein external terminals provide access to the batteries without disassembling the light. The connection of one end of the batteries to the electronic circuit is made through the end cap assembly and the housing, and in one embodiment the connection of the other end of the batteries to the electronic circuit is made through the metallic housing of a flash capacitor forming part of the circuit. In another embodiment, this latter connection is made through a conductive path around the outside of an insulated housing of the flash capacitor. The end cap and a bumper member can be used for supporting the housing off a supporting surface.
