Since somehow I end up leading my friends when I drive, I've driven in front of their BMW E46s.

The 2003 M3 w/ the Bi-Xenon headlights look nice and bright in the back and definitely not annoying at all.

The 2000 323ci with the low-beam only Xenon however, is blinding and annoying... and they are both aimed properly it seems.

Maybe the M3's a little lower?

speaking of halogen lights, those F150s, Dodge Pickups, whatever else is unbelievably tall... are really annoying when they are behind me.

onto the original problem, I would think it's the ballast too..
