Interior lights dimmings

My previous trailer did the same thing(lights dimming)for about a year before the converter actually quit.

I would first check for loose connections on the 12 volt side of the converter just in case.

That was my experience with our previous 5th wheel as well. I don't recall the name. Might have been a Progressive Dynamics. It was a three stage charger, converter much better than the original.

Yep corrosion and loose connection at battery. Clean and tighten.

Check your battery

if converter is bad were and what kind should I buy

Sometimes the converter 12V output varies when it's input voltage varies or when there are intermittent loads present. Lights are on the 12V side so they can dim when these events occur.

there is nothing else on inside
im wondering would the battery cause that...

Any other power drawing items cycling on and off? Like the fridge or furnace? Extra draw can dim the lights and then brighten them when it shuts off.

Souunds like a bad ground. Start at the light and work way to power source. Just loosening the ground screw and retightening may do it.

First thing I would do is to get a plug-in voltmeter, and watch it when the lights dim.
