Most auto parts stores sell LED accent lights in various configurations. You might be able to gut one of those to use. I think they often come with "try me" batteries that may or may not be useful for you. HTH.
I recommend this thread: http://www.tfw2005.com/boards/creative-general-discussion/774584-nano-chip-leds.html
I'm with hthrun, if you click the first link in his, I think those would act nicely with just about figures of all sizes.
eBay can have parts you are looking for Plus I remember reading jin saotome saying he buys some flashing lights toys from those cheap dollar stores and harvests the led, batteries and sometimes switches out of them
