Did a search but didnt see it again. There was a thread talking about having the fog lights on without the headlights on. I thought they mentioned you could buy and adapted to make this happen. Anyone remember something like this?

 

I believe this is the link you were looking for. If not, it still describes how to do what I think you are trying to do. Worth a shot...
