I have the current problem on mine now, I did have a headlight which was cracked at the top ( the plastic bit which screws in)
but funnily enough it was't the broken one which waas scew-if, the beam on left hand side is way up north sky high, doesn't touch road even on the 3 adjustment....the broken side was fine, looks a bit weird but least it hit the road, so i went and got a new light from scrappy and put it in fine, as expected the beam was fine. so I guess im going to have to get somone to adjust them. as its pissing me off as i have no light when driving at night ( i even upgraded to 50%+ super brilliance bulbs from halfruads)
