Headlight adjustment question

[Boxtaboy]

The headlamps look like they're popped in right. Are you sure you turned the correct set of knobs? There's a set for vertical adjustment as well as horizontal beam aim. If you turned the horizontal knobs by accident, the beam would not roll up or down at all.

Yeah, the fit to the body looks perfect, which would indicate that the aiming issue is internal to the headlight itself. The bulb is properly seated and clipped down in the housing and there is nothing wrong with the bulb itself?

have you put the old unit back in and see if it works correctly.

Yep, bulbs are in well, and the old headights still align properly when they go back in, thanks.

I am following the manual's instructions for adjustment, so that should be good. It's definitely adjusting the height of the beam and not laterally changing anything.

One thing I notice in comparison when I compare the old units to the new. On both old and new, there is a third hex socket aft of the lateral and vertical adjustments. On my old headlights, this was filled with a pop rivet but the new ones it is still accessible. What does that one do? I can't find reference to it.

Also, inside the housing under the cover is a round twist fitting below and towards the outside of the 3 bulbs. What does that do?

... still working on it...

One of the inner mounts is loose. When I took the headlight out and shifted it to take more pictures, things moved with a clunk. See pic.

Now then, how do I tighten this up? Its not broken - more of a ball and socket effect to steady things. Just really, really loose.

The round adjustment knob that I was asking about earlier seems to be the culprit, as it is proud of it's seat when I set the ball and socket properly. Turning it seems to accomplish nothing.

The third adjustment hex on the side seems to adjust the tab that protrudes through the inner lense. Thought I'd mention it.
