Where can I buy battery powered chasing LED light strands?

Does anyone make battery powered chasing LED light strands?

My daughter wants to be a volcano for Halloween this year and was thinking some amber/orange chasing LED light strands would be perfect if I could find some with the chasing feature. Seems most with this feature are AC powered, though.

Alternatively, how would I make such a think inexpensively?

LED Pumpkin necklace lights another source is here (warning.. loud obnoxious music in youtube video in the second link)

These are so cool! I may have to get a few myself...

Not that you are looking, but... LOOK A LED Flashing Fedora with Sequins

(I am so getting one of these for the next meetup)

There are some here, which say they're for indoor use only but also say they can be immersed in water, which suggests they'd probably be okay for one night in a costume.

If you wanted to build such a thing you'd need a 555 clock chip, a 4017 decade counter and some LEDs, resistors and and about $0.50 worth of other electronics. If you're cool with soldering you could probably bring the whole project in for under $15. Here's 100 orange LEDs for $4.00.

Thanks all. The ones I'm looking for do the "chasing". I think Kid Charlemagne is on to the only solution for this outside of finding one. The chasing is the thing that makes them look like they flow.

You can get an LED Chaser kit on sale now for $15. That's only 16 LEDs, however; and orange isn't one of their available choices.

I found lights for $8 at Ace Hardware, guys. :)
