Individual multicolor lights?

Question

where online (or offline preferably online) can i buy individual multicolor lights no strings attached that run off of something like a watch battery or smaller?

Thanks for any help

Answer 1

You need to look for LEDs, small lights that will run from a battery. They come in red, blue, green and ultraviolet and the you can combine these to make any other colour. You can also run fibre optics from a battery, i put the wiki links to both below.

I dont know where to advise you to buy them from as i am not sure what country you are in, but a quick google should give you a good few suppliers online, they're pretty easy to come across. :-)
