well radio shack MIGHT have them but if not and youre completely desperate try hobby stores they have little bulbs that look like LEDS ,are quite bright and have wires so you can hook one up directly to a 9V
if you live in a big city you might want to try an electronic surplus.
Toronto Canada has a big place on queen st (right near the much music building) called active surplus. The place is incredible. Transistors to LCD screens to LEDs to motors to fans to wires and theatre gels, race car seats and traffic lights. they even have a big tub of left legs from a toy baby!
