Why do some lights on Christmas lights not work?
If half a strand is working and the other half is not, you probably have a loose or broken bulb. If not, you have the more tedious job of going down the row of unlit bulbs, one at a time, and swapping them for a known, good bulb until you find the culprit. You’ll know it when the strand lights back up.

So there we were with three of our RV 12v lights not working. The first thing we noticed was all the other lights were working fine.

For instance, the light fixture above our sofa has a switch near the steps, this is also where our 12v on/off switch is located.
Is there a fuse under the hood for the reverse lights?
This is what I’ve found while trying to troubleshoot this problem, maybe someone can help me. 1) The fuse under the hood for the reverse lights is good and had power across it while the gear select lever is in Park and Reverse, but no other gears. 2) I do hear a relay snapping on/off in the dash somewhere when I remove and reinstall the fuse.

Why are the back lights on my GMC truck not working?
The “t” that plugged into the rear wiring harness went bad on mine and when I took it out of the loop that fixed the problem for me.

I finally figured out this problem.
