What could I use for a tiny power source for this light? It needs to by really tiny and be able to click on and off?

    One way would be a 12-volt smoke alarm battery, or four lithium coin cells in a stack.

    But is there a reason you wouldn't use something like this: https://www.amazon.com/iZoom-Lumen-Accent-Lights-B...

    That's double the lumens of your LED, and contains its own power source. And cheaper than your LED alone, considering you get 6 in a pack.

    How tiny is tiny (in metric units)? Are you approaching this as a supertanker builder or as a jeweller?

    YOU BOUGHT THE WRONG TYPE OF LED BECAUSE IT NEEDS AT 9V POWER TO LIGHT IT UP, AND 9V SQUARE BATTERY IS NOT THAT SMALL AS YOU WISHED.

    TO TURN IT ON AND OFF, A SWITCH IS NEEDED TO BE INSERTED IN SERIES BETWEEN 9V BATTERY AND FLAT LED PACK.
