What do i have to do, i went from having passenger side light aimed like a foot higher to now having my driver side aimed higher, when i put in a new headlight (and not happy i'm changing a light after less than a few hundred hours of use)

Ok, nevermind, i really need to get a haynes for this car. I had the bulb upside-down, which i did not know was possible. Aim is a couple inches off, but i'll take it. The knob that covers the screw on the back is for vertical aim, and the exposed screw is for side to side aim, correct? How the heck do i access that knob covered adjuster? I would like to have the aim perfect (got the masking tape ready)
