SO, I just went to an underground parking lot, checked the ground where my vehicle's tires were sitting to ensure level ground and then I measured the fog lamps (24 inches off ground) and then height of low beam projector bulb (32 inches) and then turned on fogs and aimed them a little higher (18" from ground at about 2 vehicle lengths away from wall) and then added another 8" in height to where I aimed the lower cutoff of my Xenon bulb patterns. i also adjusted the lateral movement (side to side) while I was at it. I have SO MUCH better light output now. I wonder why/how it got so out of wack, as I remember doing this same thing about 4 years ago. I STILL do not ahve my Xenons aimed as high as newer SUVs seem to have. I was driving home next to a new Lexus or Hyundai or Toyota (they all look the same these days) right after I aimed mine and even tho their light output was SO BRIGHT WHITE, their cutoff pattern was about 6" higher than mine still, but I feel that SUV had poorly aimed bulbs (just cause it left the factory that way doesnt mean it was calibrated properly, sadly).

X5Only, its a bit of a pain in the butt getting the vehicle set up against a wall to have aiming done, albeit, very easy to once you have your measurements, its sooooo worth having a nice light output, for a 16+ year old vehicle.
