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...
Forum Discussion
am not diss'ing anyone for their choices (as one commentor thinks, but took my sentence out of context) and just talking about the technical aspects of automotive lighting and noted that fog lamps in non-fog conditions really doesn't do anything other than to light up very close by.
Here are 2 lighting patterns viewed from above
This one shows, as did the one in the quote, shows their patterns projected onto pavement
This one shows their lighted distance in relationship to each other
The shortest projection are the fog lamps, which are normally in the 20 feet range, +\- a few, because projected any farther in fog will have the light reflected right back at the driver, which will blind or turn everything into a white-out.
For those who state that they are trying to light up the deer/etc on the side of the road...fog lamps are not the correct beam pattern and best to have a flood. As the fog lamps will NOT project far enough to see them, nor blind & freeze them in place. Better would be the flood lamps, which will project farther and just as wide as fog lamps.
Edit...from my rally days buzzing around with small 2 seaters out in the countryside...know well how deer are frozen and fog lamps do almost nothing. I had aircraft landing lamps, but they only have a 20 or so hour rating. Worst were the cows laying on the warm pavement...they weighed about the same or more than my 2 seater...and no amount of lighting would have helped going +60MPH down a 2 lane country road...
Here is a link to the guy who taught me much when researching automotive lighting and in this link he talks about fog lamps

These are classic lighting beam patterns to give an idea of what they are designed to do.
But...on this thread, these functional beam patterns are not of interest...just cool factor...AKA looks
Nothing wrong with that...I was talking about function and the science...and the subconscious psychology of vision vs steering vs reaction time
Edit...example of the psychology of Vision & steering.
Freeway on ramp.
If you are trying to merge and see a vehicle driver looking/staring at you...careful, they will subconsciously match your speed to create a problem.
Meaning that when driving fast and you've lit up the near ground, you'll focus there
(where you haven't enough reaction time) instead of farther down the road where you do have enough reaction time
