I just replaced all the lights in the main coach in my 36RE, the one in the hall outside the bathroom door, the one in the bathroom and the four in the bedroom. I removed the stock bulb and replaced it with this style:
G4 24 SMD 1210 LED Marine Camper Bulb Lamp Pure White Light Car 140Lm DC 12V New | eBay
It worked great and took the load off all the wiring and switches etc..
My only suggestion would be to research the type of lighting you want in your coach. L.E.D. lights come in different colors due to the power output. I found the warm whites looked better in the main and the brighter cool/blue lights were more suited in the bedroom and hallway.
Hope this helps..!
