But regardless OP if you're going to adjust your headlights, just turn each knob the same amount and you'll be fine.
Of course their part numbers aren't the same. That's not the point.
Park in front of a blank wall and look at the patterns the two lights put up there and tell me the patterns aren't the same. Then tell me what's not true.
