Not necessarily. It's more about the light pattern than the color. Fogs (such as the OEM fogs on the SD) have a short, broad pattern. Driving lights (and to the best of my knowledge, no OEM offers driving lights in North America) have a very long, relatively narrow pattern. Think "high beams on steroids" and you have the basic idea for driving lights. I've toyed with the idea of installing a bank of 4 World Rally spec HID driving lamps on my truck because I want to be able to burn the paint off the decklid of the car in front of me if they displease me, but the simple truth is I don't get out of the urban areas enough to warrant the cost of those things.
That said, I still want a fog-light-seeking missle battery for my truck so I can take out all the mis-aimed (usually Pontiac) OEM fogs that idiots run around with continuously in their Grand Ams and Grand Prixs because they're under the mistaken impression that they're driving lights and further mistaken that they look "cool".
If it's not foggy, LEAVE THE FOG LIGHTS OFF. And make sure they're aimed correctly when you do use them: fogs should be aimed low, not high.
Yeah, I get cranky about stuff like this. /ubbthreads/images/graemlins/smile.gif
