Are you talking about the exterior lights or interior lights?

Exterior, look for a blown fuse.....interior (assuming the side of the mirror in the bathroom) look for a blown GFI......

Most likely:
If it is a regular rhythm, look at your converter. The converter changes 120vac to 12vdc. Your interior light are 12v. A failing converter will cycle like that. Probably in the diode array and not servicable. I recommend one of the multi-stage converters. More $$$ but worth it. An alternator (on the engine) can do the same thing if the engine was running.

If irregular, it is varying loads on the power feed. Not much you can do about it except change where you hook up.

Not knowing the year or model makes this impossible to answer.

The solenoid is most probably for your starter ( just like an older car), what type of Coachman is this? p37 as a model doesn't come up.
