Running lights and reverse lights won't come on.

[coralcruze]

I am having some electrical issues. On my last trip I noticed some weird electrical issues.

The running lights on the back half work fine but none of the running lights on the front half work. Also the two side lights won't work even though I turn the switch on from the inside. Then on the back half the reverse lights won't come on when in reverse.

I thought it might be a fuse out... but I checked the main fuse pannel in the TM and all are fine there. I also checked the main fuse in the battery box on the tounge and that 30 Amp main fuse it fine also. Am out of ideas to where the issue might be?

Any ideas what is causing those issue?
