Headlight adjustment

[Terranical]

I've recently fitted LHD headlights (square type) to my 1994 T2 but they are too high. The adjusters (the ones done with a Phillips screwdriver) are seized and some of the teeth broken off - however, there is a large black knob on the back of each headlight which doesn't appear to do anything, does anyone know what this is for?

Re the black knobs on the back of the headlights, the words "Open & Close" are above each knob, but they are both immoveable - any ideas anyone?

Does anyone know what the large black knob ob the back of each headlight (marked "open/closed") on 1994 square headlight T2 is for?
