Last night I noticed - for the first time - that my 95 Rampside has a cab light. Mine doesn’t turn on, but it occurred to me that I’ve never seen any pictures of that light anywhere. Is that a regular feature? A Deluxe feature? Aside from a burnt bulb, any known common issues with that light? I would like to get
Mine working again.

Always good to look at the wiring diagram.Answers a lot of questions!! GGG

No door switches in Rampsides... turn headlight switch knob CW

Domelights have power ALL the time...switches control ground.

Check your door switches,and also turn the headlight switch to turn on the light.

Shouldn't that be CCW? (Counter-ClockWise)
Oh, and not just turn it, but turn it until it clicks past a detent.

I turned the light knob - counter clockwise. I could feel it click but the cab light did not go on. First thing I’ll check is to see if the bulb is good.

Bulb looks good. Filament seems to be intact. Good contacts. The issue is elsewhere.

Buy a Digital Voltmeter at your local Harbor freight!! $6

Sometimes filaments "break" at the end - hard to see - especially with dome light bulbs which have a 1/4" "end".

Test both ends of the lamp socket for power, using a electrical probe with a light with the test light wire being on a good ground. Being that one side should be live, and the other should be a ground, the test light should light on only one side. Then if you clip the test to a known good 12 volt source, test the socket again, and that will help you to determine which wire has a problem. Once you know that, the rest of the trouble shooting shouldn't be difficult, since you now know what you are looking for. The fuse in the fuse block may also be blown, so I would be checking that item first, and then move "upstream" to the light.

Checking for power is advisable, of course. And once you have power, consider this:

I changed my Rampside's stock dome lamp bulb for an inexpensive LED replacement. The difference is, um, like night and day!

That is like being on the beach, in the sun at high noon. You will need sunglasses!!!

Where did that led come from? Can you provide a link please?

Well, I used my voltmeter and determined that the dome light was not getting power. I test the bulk and it did close the circuit, so the bulb is good.

I then went to trace the electrical lines. But when I went to remove the done light, I twisted it counter clockwise to release it. Whatever was holding it in place is not there anymore. I didn’t hear anything fall, so I’m not sure if it was glued in or if some fasteners just fell quietly. In any case, there is nothing but two holes now and I can’t re-install the done light housing. Ugh.

Worse yet, the electrical lines disappear into the roof and I can’t trade them. I don’t see where they come back out. I can giggle them enough to hear them by the door frame, but that’s it. Very frustrating.

It is a common GM part, classic suppliers should have reproductions available, even (or especially) Clark's.

How do I trace the lines after they disappear into the header? I don’t see a way to access them. And it’s not obvious to me what lines they are by, say, the fuse box.

You need a free Wiring diagram from our FAQ's. Wires com down the left windshield post [A pillar ] and are the same color markings as near the bulb fixture.

If you've never done this before...time to learn

Dome lamps are traditionally orange and white, with the orange wire being the hot wire, and the white being the ground.
