I replaced all the interior lights with LEDs. I started by buying four from a local RV store for a crazy high price. I was leaving on multi-week trip and could not wait for shipping from China. The lights were a nice color, very bright and I could run them forever without battery issues. However, parts of the panels would stop working so I have had to return them several times. Meanwhile, I purchased tons of different kinds much cheaper online and through trial and error, have come up with great combinations. I suggest buying a few online and experiment.
