For that style, I think @gmbellew is correct.
Not sure on the stacked style.
I am basing that on memory of my 91, thinking the same thing- WTF aren't all 4 on ?
correct, 89-91 style have only either high or low. i have a 1990 suburban, and that is how it is with the factory harness. i think they cheapened the harness and the wiring cannot support all 4 firing at once.
the stacked headlight grille that preceded his style had lows and highs light up for high beam. that was how my old 84 blazer was.
