To make a long story short ...kinda, I recently installed new headlights in my car. I did the passenger side first & tried to adjust the beam to match up with the other. There's only the one center bolt / gear, just like the original. As much as I turned the bolt in either direction, nothing changed. This morning, I switched out the driver's lamp. That alignment seems ok. So, with the passenger side, are there any ideas on that ?
