So I was pissing with these a little more... I'm working on a project to do with a Turbo Tank I got for $40-ish.... and as an aside, let me just say that taking the TT apart is one major pain in the ass!
But anyway, I'm thinking if I can find inexpensive LED's, I think I can wire constant light ones that aren't tinted (the tealights are an orange tint and I'm wanting either a blue or white light) right into the little system these tea lights provide. The $.50 deal of a ready-made little light system is sorta kaput, but if you can find LED's cheap in bulk it's not so bad (if you plan on doing a lot of this stuff).
Hats off to Patreek for the source of cheap lights, power, etc., all wired for you though. This has a lot of applications for customizing if you use a little ingenuity.
