I'll be attending Otakon 2013 as TPA Ezreal from League of Legends and I'm currently in the process of making his foam finger:
Everything is going well, but I've never worked with lights in costumes/props before and as you can see, the eyes of the mascot glow red. I picked up some frosted semi-see-through material to cover the shape of the eyes and place the lights beneath, but now I need the important part...the lights.
I've been reading up all over the Cosplay.com forums, other cosplay forums, instructables, etc, but everything seems way too complicated for what I think is a pretty small, simple case.
I was thinking of maybe picking up some EL wire
and just coiling it beneath the material, but I don't think I can pick it up in such a short length.
I found some red dome LEDs in a local RadioShack (about 1 inch in diameter) that seem like they would work pretty well with one in each eye socket, but I haven't a clue about rigging LEDs, nor do I have any equipment generally associated with the work.
