Try connecting a ground wire to the headlight and see if that fixes the problem

I had all of the lights go out on my '28 Tudor last night. The PO had installed a fuse right at the alternator output. The fuse itself was OK but the holder was toast. I bypassed it and drove home. Did the job properly today.

Not necessarily. Nuts and bolts make lousy conductors when they start to rust.

Bad grounds can happen. I know that well.

Bad ground at the battery end can do that too.
