Ugh, the benz in the simplest fog light configuration ever...my mother, however, has the same problem. But besides not knowing what they are/how to turn them on, why are americans clueless as to when to use them. Fog, extremely hazy/cloudy/rainy conditions ONLY and in these conditions they are a MUST for highway driving---they improve visibility 100%.
