Bought another bike

Anyone know where to find a 6 Volt 25W/25W Low/High Beam Headlight Bulb for a vintage-almost antique bike?

This thing uses an ancient headlight bulb (unknown part number, since the bulb and socket are missing). I'd even settle for a 6 Volt 25W/25W Sealed Beam if I could find one (headlight would have to be about 5.25" or so)

While we're on that subject, anyone know of a supplier for 6 Volt LED Turn Signal & Tail Light/Brake Light Bulbs. I bought new Turn Signal Assemblies and what not, but obviously they're for 12 Volt Bikes, so I need to replace the bulbs in them with 6 Volt versions. If I'm buying new bulbs for the 6 Volt setup, I want LED's so that people driving 4 wheel death cages can actually see me on my little motorcycle.

I don't know what the 6 Volt Bulb Numbers would be, but the sockets are identical to 1156's (Turn Signals) and 1157's (Tail/Brake Light). Obviously those are the 12 Volt Bulb numbers, and the 6 Volt setup uses different numbers (but the same style sockets)
