How to troubleshoot this old pocket light
I have this old pocket light that doesn't seem to work. It hasn't worked since we bought our house. Other ceiling lights in the room work, but this one does not. Tried different bulbs, too.
How can I go about trying to troubleshoot this thing to get it working? It is probably from 1965 when the house was built.
I know they have LED kits to put into pocket lights, but I'm afraid if the bulb doesn't work the kits won't work either. Unless I solve the root cause of the problem.

Hi Brian, never heard a recessed fixture called a pocket light before,any way that trim will pull down from the ceiling, simply pull it straight down maybe give it a slight twist, there could be a thermal switch inside that has opened.
Post some a pic of what you find inside.

Thanks!
Here are some more "recessed lighting" images.

There are four wires that prevent me from pulling the fixture down more. It doesn't appear I can disengage the wires. But maybe I can if I dig around.

Thanks!
Here are some images...
• Where the wires come out of junction box
• Where the wires go into the fixture.
• And the place where the bulb screws in

That's an old fixture. I believe well before thermal switches were routinely installed.
Markstone mfg holds several of the patents for early recessed lighting. I wasn't aware of the company and could not find any specific information on their recessed lighting. It looks like that silver junction box may be removable to access the wiring splices. That would need to be checked with a voltmeter to see if there is power there.

Do you have a volt meter ? If so test from the screw shell to the center terminal in the bottom of the socket, also with the power off try and pull that center terminal down a bit so it contacts the bulb base better.

Thanks for the tips.
• I pulled down the center terminal, that didn't fix the problem
• Bought an electrical tester. It seems to be getting electricity. Although, maybe not too strong of a current. The tester went off, but it didn't seem to go off each time. But this could be user error since it is my first time and hard to find raw wire.
• I do have other eyeball recessed lighting from this manufacturer in the house. I might be able to take that eyeball from the spare bedroom and put into this can in the living room.
• Or if it is easier can I just switch out the socket?

Are you using a non contact tester? If so get rid of it and get a cheap analog volt meter, you can also test the terminals that are riveted to the top of the socket to see if you are getting power there,

Thanks for the advice.
Are you saying the non-contact meter will not give me a good reading? And the other one would give me more fidelity?
