The individual bulbs are low voltage, somewhere around 2 - 3 volt as I recall. They're strung together in series (voltage adds in series) to run on 120 volts. That's why the string goes out if one goes out, unless you get the ones with the fancy bulbs that bypass themselves when they burn out.

In theory, you could cut the string into 6 bulb chunks to make a bunch of short 12 volt strings, and then wire all these in parallel to run off a 12 volt battery. Seems like an awful lot of work just to avoid using an inverter, though.

I've never seen christmas light strings that run directly off 12 volts.
