I would absolutely not do wide corners on pillars.
Go BIG or go home. XL80 in spot would be my preference and is what I run. combo would be great as well but i would caution that in fog or snow, those lights will be worse than worthless, you be in a total white out. Dust as well.
If you have lower mounted fogs/combos/spots, then you’re golden, but if you have no other aux lighting, I wouldn’t go to the a pillars for a street driven truck or one that sees mostly street use.
XL80’s are like 9k lumens and I think the squadron PRO is 3100? or is it more like int the 4k. range? Either way, xl80 is 2-3x as powerful as a squadron PRO, more so for squadron sport.
I have 2x XL80’s + S8 on up fitter 1. That’s enough to be able to tell there is cat / raccoon, or smallish dog out to 500 or so yards -well beyond what my eyes are good for. Up fitter 2 has 2x LP4’s and 2x squadron pros in combo lenses. I can see the same critters out to .4 miles and I can easily tell if there are deer quite a ways off. The above lighting is good to tell there’s a human walking on the road in regular cloths to about .5 miles - I know because that’s the length of one of my streets near my house and tested it.
Squadrons sign off about half that distance and the intensity is nowhere near the LP4 or XL80.
For a short to medium distance I think you could get away with 4 squadron sports down low - wide corner and combo and if you still want more distance and periphery, throw some LP4’s on the pillars.
For more distance, you could do squadron pros + xl80s
all of that said, I would stick with spot lenses on the a pillars if you can. Combo lenses if you have to.
