Need to adjust the "aim" of my headlights. One is much higher than the other.

I noticed there's a cover over the top of the back of the headlight. Took the cover off, and noticed a screw right under it, pointing ou the back of the housing - but not sure if it'll be the one that aims the lamp lower.

Thanks for helping this N00b out!

There should be a small maybe gold knob thing. Turn that to adjust the height. I believe its located underneithe that cover, and on top of the housing.
^hope this helps!
