LED's

I have done a bit of research into Light Emitting Diodes. LED's require very little energy to run so we will be able to power them with aaa batteries which is good for space. If we wire them in series off triple a batteries, we will only be able to run 3 or 4 but in parallel we will be able to run upto 30 or 40. LED's strictly speaking cant change colour but you can buy LED's with three small LED's incorporated into them so that it would look as though it changes colour.

Would be very helpful to talk to someone from an electronics store to find out more.
