dead lights

[TC Campbell]

Can someone please tell me what are these blue crimp on's on the 12 volt lights are they fuses and is this whats keeping the lights from working?

A picture would help, but it sounds like you're describing Scotchloks. They're used to splice connections, and as they age, usually cause problems. They're not fuses.

Have no idea what you are referring to. I replaced all of my ceiling LED lights and they were all wired in using blue Scotchlocks (see photo). It must have been easier for the installers to use Scotchlocks rather than butt connectors. They are just used to connect 2 wires together.

If all of your lights are out the problem is not with the Scotchlocks. If individual lights are out, the lights may be bad. My lights started to fail due to overheating. There was a recall on them that Jayco never mentioned to anyone. I contacted the manufacturer and received enough lights to replace all of mine. I have attached a picture of the defective light.

If you want help, please give us more info as to that your problem is and what you have done to troubleshoot.
