Vertical stacked are pretty uncommon.
BB did in the '70's and into the '80's until they went to rectangle or square units.
Crown had an option for four headlights that put the second pair where the turn signal would normally be and the turn signal was centered in the black stripe below the windshield.
There were some Gillig buses that had what looked like quad headlights that were sort of stacked back in the '50's before quad headlights were legal. I say stacked because they weren't really in a straight vertical line. The second pair were fog lights that were the same size as headlights and were generally yellow. As for the rest of the Gilligs that had dual quads, all were horizontal and none were vertical.
I don't recall if any Thomas, Carpenter, Wayne, or Superior ever had vertical stacked dual quads.
