Two things: Wasn't a dumb question - the dumb ones are the ones not asked, right before something gets blown up. But for your purpose, you don't need a relay. Second, you should have an inline fuse, and I'd put it in between the switch and the power source, that way the switch is protected as well, and if for some reason the switch shorts to ground, your source (battery) is protected. Now, the size of the fuse and wiring depends upon the draw of the headlights. Wire needs to be rated at least what the fuse is, but never a bad idea to go with larger guage - but is an awful idea to go with smaller. The point of the fuse is that it is rated equal to the draw and surge of the components, never more than. Now for a really dumb answer: A relay is where people run around a circle and hand each other a stick because they have nothing better to do. LOL, and have a nice night.
