Following this thread since we have a similar problem in our trailer with the LED dome lights mounted on the underside of the cabinets over the head of the bed. The fixture has a small pwb with an LED array and a push switch in the middle of the lens. It is the same style used throughout the trailer and is fine for ceiling lighting (other than you have to hit the switch dead center or it gets stuck)but too bright for over the bed.
Ideally I would like to find a replacement fixture with brightness control (or at least not as bright) so the existing 12V wiring could be used.
