The arm goes through the rubber seal/gasket and attaches to the headlight mechanism with an M6 bolt. There are bushings in there that may be out of place or the mechanism may have been reattached with the arms mispositioned.
I might start by just checking there but, remove the round part of the rubber gasket covering the armature (outside of the bucket in the trunk) and loosed the 10mm nut and remove both arms from the motor head.
With the arms off, cycle the headlight motors by turning the lights on and off. Reattach the arms, aling them properly and snug down the 10mm nuts again.
Just a hunch.
Here's a shot of the area I'm talking about...
If you look, there's a smaller secondary pivot arm. It may have been in the wrong position to raise the light when you attached the headlight mechanism to the armature.
