    Dimmable led lights?

    Does anyone know if the cabin lights can be dimmed using a dimmer switch?

    I believe if you replace the main ceiling light switch with the proper LED dimmer switch they can all be controlled by that switch but not individually.
    We have thought about doing that for the ceiling lights, which we'd don't use often because they are so bright and the LED strip at the awning.

    I installed 3 of these in my Momentum. One controls all the bed room lights, one for the bathroom and one for all the garage lights. I have been very happy with it. Click image for larger version.

    HERE is a LINK to help for the dimmer installation.

    I just did it to the living room of out 374TH-R Solitude. Works great. KEN

    Traveldawg posted these instructions. Worked great for me.

    Both grounds on the switch go to the ground inside the wall. The "IN" 12v wire connects to the hot wire on the existing switch. The "OUT" 12v wire on the switch goes to the lights.

    So if you measure the 12v at the switch one side will have 12v and one won't WHEN THE LIGHT IS OFF. The 12v hot wire is what goes to the IN on the dimmer and the other wire goes to the OUT. Like Jim said, find the white wires in the wall, they should be the ground.


    The white wire was down below the switch sires. KEN

    There are multiple options. I went with installing the dimmers for the ceiling lights and awnings in the main switch panel. See this link for lots of discussions on this:

    A picture of my completed panel is in reply 56.

    Hope this helps.

    That's the same system I went with on my Imagine 2400BH. The LED lights inside the coach and under the awning are SO MUCH more usable in all kinds of lighting conditions - and campground neighbors appreciate not having NASA runway lighting disturbing a quiet star-filled night I purchased the mounting plates through this website where folks upload files for items they've 3D printed - and now people can order the items to be printed for them and shipped once complete - this site was referenced by user Jim @jh.xsnrg in the Mods & DIY forum: ThingVerse.com Grand Design Dimmer Switch Adapter

    Only issue with the dimmer... When on DC power the interior LED's flicker at the dimmest setting but when on shore power the dimmer functions perfectly.
