Although LED strip lighting looks more spectacular, I couldn't help but notice these little lights the other day when I was nosing my way through the aisles at Home Depot. They are called Dot-Its, by Sylvania. They are meant to be decorative note-holders, lit with SMT LED's and powered by a lithium disk cell.
These lights are really quite bright, and you can select a steady or blinking mode. They have an adhesive backing, but they also have strong magnets in them, and cling to the screw heads beneath the motors without falling off.
The pack of four cost just $ 10.00 (CAD), and although the cells would probably cost a lot to replace, it wouldn't take much to wire them in permanently with the appropriate resistors.
