Fair enough, we don’t have inspections here and the only state laws for my state that mention fog lights simply say they have to be less than 30in from the ground. Obviously I’m not familiar with all 50 states laws, but for lighting I’m fairly familiar with my own state and a couple neighboring ones(started modding lights on my cars in high school so tried to keep up with the lighting laws to stay legal). I’ve never seen an actual law stating that fogs and highs can’t be used together but always good to learn something new.Cookie, actually it is a law that fog lights have to turn off when high beams are on. At least here in PA it is. Car will fail inspection if it operates any other way.
