I did raise the vertical adjustment just above the horizontal line drawn on the wall in my garage, just waiting for night time to give it the real test!
A rule of thumb for those wanting to adjust headlight is
1. 25 feet back from wall, place center of front tire on this line
2. Measure from ground to center of headlight
3. Transfer that measurement on to the wall, draw horizontal line
4. Beam should hit dead center on horizontal wall line
In the case of the Osram bulb I brought the beam just slightly above the horizontal line.
