You are correct - you absolutely should NOT be using high beams in fog as your driving lights. In fact, using WHITE lights of any sort will produce more "blinding" glare than the preferred yellow, which my DRL's and fogs are.


I was "using" the fog as a display screen of sorts to visualize and evaluate the projection angles and beam width of my various lights and discovered the DRL high-beam was completely skewed. I probably could have worded that better in the question.
