Looking closer at your pics notice on the third one with the one light super bright? All the energy that want to go through the bad ground is back tracking through the headlight that super bright. You problem most likely on the passenger side, definitely check that all the bulbs are in correctly and not either swapped with another bulb or in backwards. If one is in wrong it will be more difficult to pull out than normal.
Yes, a ground and/or both a bulb in the wrong position too. That up and down window thing I have seen happen on a low voltage situation. You are having stray electricity running around the system that can cause strange things to happen. When you say grinding, what do you mean, the window motor?
Let me know,
