Keith,
You are getting 12v but probably not enough amps to light the bulb.
It doesn't take much current to drive your meter but much more to heat the
bulb filament to where it glows. I've seen this on some of Alfas - got
current but no glowing light.
I'd investigate each wire connection that goes to the oil pressure
warning light. There is one (or more) in there that is corroded to where
you are losing amperage.

Got everything working again, new inline fuse working fine. Nuetral
light working again. Oil Pressure warning light - still not working. I
can't figure out why. I have continuity from the inside tab inside the
bulb housing (the one that the bulb tab depresses) to the wire
connecting to the oil pressure switch on the left side of the engine. I
checked the speedo to make sure 12V is going to that bulb and it is. I
also checked for 12V on the wire connecting to the oil pressure switch
and it is there - the way I checked it was I pulled the wire off the
switch, inserted my meter probe, switched on the key, and voila, 12V is
there. Can it be my oil pressure switch is bad? Why else would that
bulb not light if I've got continuity and 12V is in the line?
Stumped.
