LEDs and watch batteries Make anything light up with a bag of cheap LEDs and some CR2032 3-V lithium batteries. Just tape the leads of the LED to the battery (the short lead connects to the negative side) and attach to your model car or kite. Or add a neodymium magnet for an “LED throwie” that sticks to any metal surface.
