A flexible cable light capable of generating a visual effect of flowing water has a transparent inner coating with two strand wires, multiple circuit boards connected as a string and held in the transparent coating, and an outer transparent coating that encloses the inner coating. Each of the circuit boards has multiple LEDs, current limiting resistors and at least one LED driving chip. The power wires of circuit boards are connected to the strand wires of the inner coating. The signal wires of LED driving chips are connected in series and coupled to a controller. Each LED driving chip has a serial shift register and an outer register and provides three large driving circuits. The control signals for the flexible cable light can be enhanced and repeated by each circuit board. Therefore, the flexible cable light can be lengthened to any desired length.
