This question remains mysterious to me. And I can't get any answers on the net. WHERE are those screws? Are there Vertical and horizontal screws? Share your experiences. Is it hard, dangerous in terms of reversability? I have HIDs and they illuminate all the way to space. I want to aim my lights somewhat downward at least to offset the glare. Any ideas?

Normally they are on the top right where the light goes into the car. I don't think that they are that hard to miss if you look for them.
