what should I use for a power source?

Im adding some fog lights in my 2002 caravan. what can I use for a power source? can i tap the regular lights or the wiper motor? I want something that will shut off with the car if I forget to shut them off. Thanks

After a few emails I was convinced to add a relay to the package that I bought to add some more lights. All in all it was pretty easy and worked out well. I did buy a better looking switch though because I didn't want the red switch inside the van.

Is it possible to post a brief how-to?

Thanks, T
