Hi just a quick question, I have a 1985 190E, aren't the fog lights supposed to come on independent of the headlights? If you turn the Park/turn signal lights only to the on position and then pull the light switch out that should turn on only the fogs and not the headlights, correct? My lights don't work that way. It is either all of the lights are on or none are on. Everything works correctly except for that feature. Can anyone explain what is wrong or if this is the way it should be and a possible way to address and correct. Thank you.
