And you teach electricity?

Well IMHO, that is better than an intermittent problem!
If you've got 13 volts at the bulb and a good 12 volt bulb, what's left?

No, now they're out full time:^)

If you've got 13 volts at the light bulb end of the wires, then
the
problem
could be:
1. faulty light bulb(s).

Did that.

2. faulty light socket(s) (perhaps oxide has built up on the bulb,
the
socket, or the wire ends, which could be the resistance you
mentioned).

Did that.

3. faulty light switch(es) (pull the bulb out and check voltage at
the
socket; make sure the switch is in the ON position).

Did that.

4. loose wire (make sure all terminals are oxide free and tight.
Since
you
have more than one light in this circuit, I'm going to assume they
daisy
chain (jumper) from one fixture to the next, make sure all wires
are
secure
on all 4 fixtures.

Did that. No longer intermittant. Bill's really happy about that!

So the aft-most two dome lights (12 volt) on a 4 light circuit
have
been
giving me the blues for a month or so. Intermittant most of the
time
but
now dead, sort of... Bill replaced the switch on one and they
both
worked
until he left town...After another day of meters and torn up
galley
seems
he's getting 13 volts through the wires but it won't light the
bulb...He's
thinking there is some sort of resistance somewhere. Any
ideas?
Experience? Jokes?? The Taiwanese in their infinite wisdumb
epoxied
the
wires into the deck beams and cabin sides!!!
