if you mean you want to have a UV led that flashes at a constant rate powered by usb you want to: use a 555 timer IC to make it flash get a old usb plug from a extender or something use the red(positive) and black (negative) wires form it to power the IC get some LED's form maplins or ebay or somewhere and use the appropriate resistor so they don't explode in your face have fun and good luck
