Stop in for a cup of coffee

Hm,... I guess i answered my own question. It is a Sylvania SilverStar bulb, and on those it seems to say Performance on the glass under the Sylvania name. So, it seems it is a regular bulb, not even halogen. But, maybe a little whiter light than it was out of the factory in 1965.

I'm running Nighthawks. Have really only been out in the dark with it a few times, but thought they were great. Giving them full power via relays and (IIRC) 12gauge wire helps a lot with light output too.
