I've never actually found out: Do "fog lights" really cut through fog? Most of the time, they are just used to look cool.
Yes indeed they do. And yes indeed they are. When it's so foggy that you find yourself rolling down your window to stick your head out to get a bit better visibility, _that's_ when having real fog lights (extra wide patterns with a sharp top cutoff, and not those stupid Subaru and Dodge pickup floodlights) can really help keep you on the road. And in those circumstances it can also help to be able to turn off the headlights and run only on the fogs. Days when you wish you could have stayed (or already be) home. -- Jim
