It is probably just a static spark if you can only see it in the dark??? Try sticking a piece of contact paper around the USB port (or ports) by carefully cutting out holes around the USB ports, this should act like an insulator and keep this from happening, you may have to double up the layers if it is a strong spark..? Or unplug what ever the USB plug is from first if it is a powered devise, and see if it still does this???
