im not really understanding what B is...
B. This is the amount of slope the headlights have to meet DOT specs. At 25ft, the lower step of the cutoff should be 2.1-2.5" below the middle of the projector, which is the reference line in red that you marked using the masking tape previously. Check each headlight seperately to make sure the lower step falls on this line.

(b) = (new distance/25 ft) * 2.5
hope that makes sense.
(b) = (new distance/25 ft) * 2.5
hope that makes sense.

Its weird whenever I turn the screw on mine, in either direction, I cannot actually get my headlight beams to raise or lower, and unfortunatly my HID fogs are currently pointing like my headlights should be, and my headlight HID's are pointed at the floor right in front of my car. Anyone have any suggestions ?

so this will remedy any recalled 06+ lights floating out there? you would think if it's just an aiming issue, they could do the adjustments under warranty? shirley there must be some sort of build quality/issue they're replacing these left and right instead of re-aiming them. what would be the difference between updated 06 lights and re-aimed lights? if not a huge difference, may be worth picking up some defective ones and adjust per the post.
