2001 left/right headlight adjustment(where is it)??

Hey guys,
Happy to say my 01 with now 153k is running strong, just replaced right caliper. i put HID's in it and it looks great, light cutoff is suprising. I am adjusting my lights (they were out of adjustment when I got the car) but where the heck is the left/right adjustment? Looks like there is an area on the light made for it but nothing was installed there.
Need some help with this. I got the lights adjusted down just need left to right.

thank you,

Scott
