On my previous cars with fog lights, you were able to have only the fog lights on(along with the parking lights). The only way I can get them to come on with this car is to have the head lights on. This defeats the purpose of the fogs doesn't it? If it is actually foggy, the headlights illuminate the particles in the fog, reducing your visibility. The fog lights are set low to avoid this. Am I missing something here? Can I have just the fog and parking lights on without the headlights? Or are they just for looks?
