1992 Corolla right tail light not working

1992 Corolla-274000 miles/automatic. (Brake light-in same socket as
the non working tail light- and all other lights work good)
I have 10 volts at the socket (from bulb contact to socket edge-
ground) and 10 volts if I use a second ground (no change). Removed the
bulb contact disk from socket, touch bulb to the contact and ground
the edge of the bulb with a seperate wire and I get same result (tail
light won't work - brake light works. I'm confused - seems like I have
a complete circuit, but the tail light bulb won't light. PS - I was
using three different known to be good bulbs while doing this, type
1157. Please Help, don't want a ticket, thanks PullnGo.
I Will Also Add: The tail light bulb is an 1157, so it has
two elements - 1 for tail light and 1 for brake light. So it is one
bulb that has the tail and brake light in it. The socket that the bulb
goes into has two contact points, this socket has two power wires (one
for tail light and one for brake light) and a ground wire (which shows
a good ground) going to it as well, but no tail light - Hope I didn't make this too long winded...

Sounds like a partially open power feed wire or connection; that when the bulb is installed and a load put on the circuit (lights turned on), something is going open. (Loosing connection)
Maybe try using a test light for the testing of the circuit; why I say this is that a high impendence voltmeter will not apply a load on a circuit; it measures potential voltage on a circuit but does not take anything away from the circuit. A test light uses current flow to light its bulb; this current flow will apply load.
Have the test light lead clipped to a known good ground. With the probe start at the socket’s tail light to bulbs contact. If the light doesn’t light move to the back of the socket and test the (I believe) green wire, leading into the socket. Keep moving away from the socket until you can get the test light’s bulb to light. Once there you’ve found the problem; it could be a corroded wire, where the insulation has become damaged allowing the copper wire to rot.
If by chance the test light does light at the sockets contact with the bulb removed; try reinstalling the 1157 bulb and then test the green wire. The test light bulb by itself may not be enough load on the circuit to cause whatever to go open.
I don’t think the problem will be to far away from the socket; because you said all other tail lights are working; this same green wire feeds all of the rear tail, marker and license plate lights.
You may end up probing into the actual wire with the test light probe; if so, make sure you reinsulated the puncture holes with a bit of silicone.

A+++++++++++++++++++++++++++++++++++++++. Mr. Dan. What can I say except - "PERFECT". I followed your Direction word for word and it went exactly as you said. There is a connector just inside the body (behind removable jack panel) about 8 to 12 inches away. The Green wire had a bad connection on the opposing side. I securely repaired the connection and siliconed my test spots  . I went  when my test light nearly blinded me where the wire could take the load. I rely heavily on my multi-meters for testing. I had to make up a test light from and old car socket and bits of wire. I'm going to buy a decent test light now (Thanks to you). You light up my tail light, da da da da. Thank you so much - No tickets for the 274000 mile corolla today! Thanks Again, Carl.
