Should be 25' from a wall. Then look to see where the cut off (top of the beam pattern is). It should be 2"-4", if memory serves, below the center or midpoint of the beam's source which will be you headlights. A simple tape measure from the ground to center of the low beam housing will provide that magic number. If you are no where near that and they can't be adjusted to meet that then they will be no good. When I did my HID replacement a couple of months ago, the measurements and pattern were spot on with no adjustments needed. You can perform the same steps above with your halogen bulbs installed just to verify there is nothing wrong with your headlamp assemblies or housings. If you halogen bulbs provide the same results you may have a problem like a broken tab or mount on the housings or the adjustment screws, or whatever.Your best indicator is drive up to a wall at night about 10 feet away and take a pic and post it here, then we can really see if they are any good.
