My MBenz has factory yellow fog lights and they don't blind anyone.
Driving lights are more blinding than properly installed fog lights.
That is my experience also. My Dodge Sprinter (Mercedes van) has factory installed fog lights. They do not blind oncoming traffic. I normally have them on whenever the lights are on. Although I rarely drive in fog I find them very useful to light up the side of the road all the way to the fence line. We have a high deer population in this area and I find the fog lights to be very useful in spotting them at night when I can't be using my brights.
I hate driving lights because they always blind me.
