1999 civic headlight adjustment

I just purchased a 1999 honda civic LX. The headlights require major
vertical adjustment (down).
I have found the horizontal adjustor but can not find the vertical adjustor.
Can anyone help?

 

I have a 2001 Accord and have noticed, with the hood, up that there is
on the top of the headlight assembly, a double headed arrow with a U
at one end and a D at the other end. On the back of the light
assembly, near the arrow is what appears to be an adjustment screw.
Look carefully for the arrow and letters, it's not obvious.
It appears that you adjust the beam height by adjusting something
inside the light, not the whole light assembly.
I hope this helps.

 

Where did you get the manual in pdf format? I see that you can navigate the
main menu and table of contents.

 

I work at a dealership. I shouldn't really be releasing this info.
