Both of my running Benlys are 1966 C95's, not CA95. All of the C95 headlights that I've seen have reflector/lens units with replaceable bulbs. I have only seen one that had the bulb sealed into it. Out of curiosity: were these bulb/reflector/lens sealed units only used on the CA95's?
If you can find them, GE #2330 dual filament headlight bulbs fit the replaceable lamp units perfectly. They are 6V 32/32 candle power and I'm guessing are probably from auto use in the 1930's or so.
