Interesting LED light issue

Our dinette slide has two LED lights overhead. A couple of times this week the LED light in one of them was very dim, like low voltage. All others were fine. They are on a separate circuit from the main overhead lights. One time I turned it off and back on and it was fine. The other overhead light was bright, although once they were both dim. Once the weather gets warm enough I'm going to see if I can find any loose wire underneath, as the electrical cable must have to flex back and forth with the slide. But wondering if anyone else has experienced this situation?

Make sure the light is wired correctly, no loose wires. If so, try replacing the fixture.

This is the first time I have seen this happen, and we have been camping in this trailer a lot. The overhead light gets a lot of use as my wife uses it to read by. I do suspect loose wires somewhere though, and again, will check that out when the temp is a little more comfortable. Confusing part is that most of the time it was just one of the lights, not both. Just once they were both dim. Always something.

I had an issue with my Palomino TT with the LED light had a loose wire. I soldered it back on the all was fine from that point on.

Could be a bad contact in the switch causing a high resistance that is corrected by operating the switch a second time.

This is my thought as well. Since there's so little load on the circuit, it doesn't take much of a bad connection to affect the light output.

x2 sounds like switch may be bad.

That is a possibility, but the overhead lights in the slide out are not on a common switch. They are turned on and off by pushing up on the middle of the light. Now most of the time the problem was just one of the lights, at least one time the other light exhibited the same problem. I just need to get in there and take off the covers and have a look see and hope to find a bad connection.

I had a similar problem with the overhead lights in my unit. Since the led lights are very low power usage they are very susceptible to a poor (light) connection. I also would recommend that you start at the light fixture and ensure there are no light connections.
If that does not work look at the fuse panel and ensure that the fuse is plugged in correctly. In my case the fuse was plugged into the holder properly on one end of the fuse but the other end of the fuse was above the socket therefor making a light connection.

Most 12 Volt lights are "piggybacked", that means if one fails you want to start troubleshooting at the splice if you can.
We had a couple wiggly connectors on LED light strips in the bathroom tow kick lighting and in an accent light over a window in our RiverStone causing the exact same "works, works not, dim, bright" scenario you're describing. I simply cut an inch out of the light strip and crimped the connector back on tightly, yours may be different but this gives you an idea.
