Re: headlight adjust
Ok, so you are turning top dial to aim higher and went too much, then aim slipped down?
If that's the case, first aid try may be different way.
when you try to aim high by top UP/DOWN screw, you are pulling top clip toward back of housing, which mean opposit direction from clip fall off from the tip of adjuster rod.
So top clip went out from rod is hard case to think about.
Possible case is that you may have stripped thread( of clip since it's softish plastic), then slipped, possible went off from rod?
Normally top clip goes off rod when you try to aim low too much.
Does inner structure wiggle easy?( grabbing projector back or high beam insert to wiggle)
grab by back of projector or high beam insert to see if you can move projector unit by hand,
if it moves,
clip isn't working
If you did broke clip, only way to fix is open headlight up and replace clips.
I have few clips around if you needed in case you decided to open and try fix.
General aiming method that you can try by yourself is adjust and drive method.
This is that I posted for 2010 thread, but it saying same thing for general idea how you want to aim.
Ignore about green circle mention, it's only for 2010 model projector.

Yes, pretty much "direct straight from each headlight" is easy way of understanding. for detail, you can look up "how to aim" thread somewhere.
But unless you have headlight aiming tester, their diagram is kind of useless(not practical) information.
I usually try to aim like following pics.
Just my personal guidance though..but this is what I believe aiming diagram saying in "without tester terms"

top left is your basic projector's beam pattern, center of beam should be brightest and also along cut off line, good amount of light is focused.
On the wall, both elbow point height should show same height.
and right top pic, both elbow point should land on the ground within about 40m( if you want more lighted area, you can rise aiming little but more you raise, less intensisty on the road lighted area and if you can't see elbow point land on ground (at dark street), your aiming is too high.
park your car along the long wall( like back of wal-mart or something, wall is on your LEFT) you want to see your beam cut-off line going(sloping) down.
If you see your beam line and ground parallel, aim is way too high.
This is my "usual" guide for aiming, use this as reference and check yours if it's within normal range.
