Headlight help

Great, thanks.
I'll get the electronic regulator tomorrow, which is the only thing I have not replaced, other than the alternator.
I have been reading many threads on electrical systems, and I have wondered what alternator I actually have, and what I really need.
Maybe I can locate a starter-alternator rebuilder who can help.

As far as the bulbs, those places did not have them for a while, so I went to e-Bay- I wish NAPA carried these things!
