I have a Sundowner horse trailer with LQs. The overhead light is were we think the noise is coming from. It starts low then gets loud enough you can't be in the trailer.The sound is like a fire alarm when the battery is dead. My husban has checked the converter it seem to be working correctly, the input and output have the right voltage reading. Help!

Incandescent bulbs or LED? My LED lights will make a slight buzzing sound nothing that will drive me out of the trailer, it only happens when plugged in to AC power.
