Fog lights on w/ High Beams, New GM trucks
Works just like on the last couple gen trucks. New 2020 Silverado Will see how much it helps. Last Chebby, 2016 model, it was night and day difference (pun intended, lol). Well not quite, but...

My experience is that the quad headlights where the low beam stays on with the high beam give the best overall illumination, the low beams still give a wide spread to see the sides of the roads, while the high beam project out.
Once cars started going back to a single light on each side, the high beam doesn't give good side illumination. That's where the "fog" or whatever you may want to call them beams come into play and give and advantage of good side illumination,
projector headlights are even worse in some conditions since the upper cutoff is so sharp. so on a slight uphill visibility is reduced, and high beams if ok from a traffic standpoint overcome that, but then with no seperate low beam, the fog light really helps fill in.
And just because high beams are on doesn't mean one is going fast. Around hear there are many roads with a 35 or 45 mph speed limit with almost no traffic, so on go the high beams.
and having grown up in areas with lot's of wildlife (4 legged kind) I agree with Grit dog, ANYTHING to see them and keep them in the ditch is positive.
