If there is nothing else that started and is running when this happens then I would suspect a corroded or loose ground wire or any of the other wires that might be connected to your lights. If you have very old wiring
then it might be suspect. I hope you can find the culprit but first check out ground wires.
If they all flicker and dim at the same time then there is one common wire problem. If it is just one light or maybe just the lights in the galley
or just the cabin then you can assume that a common wire to just that space is not connected correctly.
You did not mention what kind of lights you have. There are several different styles and what you have said so far is that they are 12volt. They could be flourescent, led, or halogen as well as just 12v auto style bulbs.
Good luck in your search.
