A current-seen cable, includes a main cord as a power cord or a signal cord and a plurality of electroluminescence cords, said a plurality of electroluminescence cords are arrayed abreast and are intertwisted helically in sequence to be a electroluminescence cable which is insulated from the main cord and emit light section by section, in which every electroluminescence cord is controlled by a driver working in synchronization with the main cord to emit light in sequence. Said current-seen cable is driven to emit light by a plurality of output drivers controlled by the program-operated chip. When the main cord is live, the drivers work synchronously, then each electroluminescence cord emits and dies light periodically under the control of program-operated chip of the driver, and as each electroluminescent cord is intertwisted helically and people can only see one side of the cable visually, said whole cable is shown as a kind of lighting phenomenon in which a lighting section (or a lighting dot) of said cable goes after another section (or another dot) next to it. The visual direction for going after light is same as the direction of the current flowing in the main cord, so it can indicate the direction of power input and output.
