Yes, you can put a camera there. Search around on the forum. I know of at least one guy that has done it. I can't remember his screen name at the moment though. I'll post if I can find it.
Edit: Found it. Here's a link to his album.

Well, duh me. He didn't put in in the fog light, he put it in the plug right above the fog light. You probably wouldn't want to mount a camera as low as the fog. You wouldn't get a real good view of things.
