Speaker feedback when certain lights are on.

I have a 2007 Rockwood signature ultra lite. I have several lights in the unit that when turned on they create a humming noise through the speakers. This does not happen with the rest of the lights only just a couple. This only happens when the concertone system is turned on.Has anyone else experienced this and if so what was the fix?

So what is unique to the lights that cause the interference? Maybe those are the only LED lights in the trailer. Are they in a certain location? Getting that info is a good start.

far as I know there is no difference with these two lights, except they are towards the rear of trailer. could it be a ground issue?

OK. Does it only happen when the sound system is turned up, or is it independent of volume? Turn the system on but turn the volume all the way down, does it happen then? How about what is playing on the system. Radio, DVD, CD, ?
