OK, since there's so much talk about the different relays on board our wonderful cars, and also talk about "wiring in a relay" when using higher wattage headlamp bulbs, I need to ask the obvious question...

What function does a relay serve and how does it work?

I'll take a ration of muck from the list if it means getting this question answered.

Thanks folks,
