WTF you don't need a 13V battery. I have found these battery's can be found on eBay for $3.00 for 20. Also you can find 20 LED's for about 3$ in red blue orange and green. Just search lithium button battery's.
You can get them at any electronics store such as Radioshack, but it is much cheaper to buy them in bulk online. I bought from ebay, but the instructables link I put in the video description also lists some very good sites to buy from.
would it be possible to put a solar cell on it and make it waterproof... therefor last wayyyyy longer ?

How long do these typically last (with the CR2032 and a 5mm white LED, lets say)?

The text says "1 3V battery" not a "13V battery." Admittedly it might have been smarter to write "One 3V battery," but that's hindsight for you.
