| Used to make red and green flashlights with LED's soldered to 9v batteries. Purloined from work long ago. The shame of it! Never bothered with resistors, they weren't made to last forever. Scared the crap out of a room mate once, making UFO noises(your guess is as good as mine!) and having the lights appear out of the dark. Tsk, tsk.
