I just noticed a product I've not seen before over in the Camping World store. Haven't looked for it anywhere else but since it's a generic "Diamond Group" product it will probably start to show up on other sources.
I think it's built to dim cabin LED's (which I'm thinking about on in my main living area) but it looks like it would work for the awning LED strips as well.
Cheaper to just replace the oem white strip with a white or a color strip with remote that allows dimming and multi color option. Did mine this summer when the oems died. Cost less than $20 and very easy to mount and wire up.Got them via Amazon.
I was going to order what bassdogs is talking about this weekend but I like that switch with the lever control. It looks like OEM. Not sure if I have space it in my switch panel though.
OEM look maybe but the only thing you see with my strip replacement is the original on/off switch in the control panel. The dimming and color selection are done with a thin small remote that fits in the tray on the out side of the control panel door. Bought a spare remote for $3 or $4 in case I lose the original.
You will have a problem with this switch if the ground coming back to the light is not a dedicated ground. Most rv circuits are grounded thru the frame and the wires on the switches are more or less a common frame mounted ground. If that's the case the dimmer switch won't work. You run into the same thing with most replacement led strips unless you splice the power back to the original strip wiring. Read reviews from the same switch on Amazon.
I got mine during the week. Haven't installed it yet. Was thinking of getting another for the awning lights. I want to order a new panel insert so I can re locate the controls and mount the dimmers side by side.
