The point of the lights evidently works, doesn't it? You obviously SEE them. (Don't get upset, now, I'm "kidding" you just a little bit.)
I use my fogs as DRL's 'cause I want my car to be seen by other drivers. 'May be a little much, but uninsured fool suddenly turned left across in front of wife several years ago; totaled our 80 240D; fool said he did not see the 240D; bright, clear day; cars only 50 feet or so apart going toward each other. If the other driver sees my orange lights, maybe he/she won't "do something stupid" and hit me, or if I do something stupid, maybe they can get out of the way.
