Cause of dim then bright lights

The lights in my rv dim after being on for a while, various time. Most of the time they will eventually return to normal brightness after and for a while. But, I can get them to return to brightness by activating the push button for one of the slides some of the time. Not enough to move the slide but enough to make the power loss evident to the converter. Sometime they will get bright again when a floor heater turns on or off.? Is this an indication of a failing converter, short, or????
