An illuminant USB cable is constructed to include two USB connectors, each USB connector having a light permeable housing and a circuit board with a LED that emits light when the illuminant USB cable connected to a computer, a cable electrically connected between the circuit boards of the USB connectors, the cable having a light permeable tubular outer shell, and a fiber optic axially mounted within the tubular outer shell of the cable and connected between the light emitting elements of the USB connectors to receive light from the LEDs of the USB connectors and to refract light through the outer shell of the cable to the outside, the fiber optic having recessed portions for producing light spots when refracting light from the LED.
