Seneca 36fs electrical/lighting problem

hoping that some of you may have heard something about this and will have an easy fix!
We recently purchased a 2008 Seneca 36fs, and we're currently on our first trip (in Florida). I've pretty much managed to complete most of the work needed to avoid a trip to Camping World at this point, but this one has me stumped.
When I turn on the vanity light in the bathroom, and/or the fluorescent light in the bunk area, and/or the fluorescent lights in the back bedroom, the coach goes into what we call "Disco Mode!" And all the lights and power intermittently starts to flash (we also get a beep from the Carbon Dioxide Monitor every-time they flash).
Now, if I turn on only the bath vanity light, it happens every once in a while. If I turn on 2 of the 3, the flashes are more frequent. But with all three on, "Disco Mode" is in full effect.
I'm figuring it's a short, but from where? And why does it increase when the three sets of lights are on?
At first I thought it was the transfer switch, or a bad connection at the 50
Amp connection. But I checked all of those, and they seem to be fine (I'm not an electrician, so by checked I mean wiggled the wires to try to duplicate the effects).
Any ideas?
Thank you in advance for any help!

Make sure the 12v fuse is tight. If it's loose the heavier the load the more it would arch. Could also be a bad fuse for that circuit,

Your mentioning fluorescent lighting. Are the light fixtures old enough to have a small round cylinder shaped device (a 12V ballast), tucked in around the bulbs? I know the fluorescent lighting industry has changed in recent years and changing ballasts are becoming a thing of the past. However, my old 5er had the fluorescent lighting and when I would get the flicker/disco effect, it was solved by picking up a new ballast.
