Wow, those are bright for 158s. Did you do anything special to get them this bright? Just contact cleaning?

I was surprised myself.
The only other thing was to tweak some of the contacts on holders that didn't seem as snug when installed.

I can't think of any other repair or cleaning that would have had helped , except maybe adding a parallel alternator feed to the ammeter.
