LED Wing Light Question

[nippaero]

I remember seeing somewhere on this forum the measurements for adjusting the landing lights. Now I can't seem to find them. Can someone point me to them again?

EDIT:
I found the diagram I was looking for. It was in the electrical service manual. It may be posted somewhere else on this forum as well.

I've adjusted those things every which way but it never seems to make any difference.
