Perfect in my RV application
Worked perfectly in my application. I used it to dim an LED light strip that was too bright in my RV. Now we can turn it down to an extremely low level or crank it up to full brightness. The only comment I have is that in my application, I first wired it backwards, which is very easy to do. The dimmer only dims if you install it the right way.

12 volt dimmer switch
I received the product and tested with an continuity tester and the switch did not work. I hooked it up anyway and the lights stay bright and will no even turn off I went to the ace hardware bought one hooked it up and worked great .bad quality control.

A solid rheostat especially for the price.
I bought this with a 6 pack of 6 LED puck lights to install in my Cargo conversion trailer to operate on an off grid or plugged in and inverted scenario. I bought a second 6 pack of puck lights so my rheostat currently operates 12 lights and it works well. The rheostat seems to be of decent quality and works well with the lights. The switch has a positive on/off detent and a smooth rotary action through out. The one thing I don't like is the the switch housing can rotate inside the switch plate once installed if the friction nut becomes loose. Not a deal breaker but something to think about when installing. The jam nut needs to remain tight. So far very, very low level of flickering and only briefly while adjusting. I would buy again. Price point out allows 5 stars.

Can dim my RV awning lights now
It worked for what I need, but would have been better if the shaft on the pot was longer. If using for RV dimmer, maybe get a different one

Good switch. The dimmer is good.
Exactly what I needed. I had this wired to a box for an led bulb. The instructions were simple enough and it took very little time to set up.

Great for RV or indoor low voltage lighting.
Installation instructions are easy to follow and versatile with on/off click at the lowest setting. I keep buying this for all my 12 volt lighting projects.

Great Dimmer for my RV
I bought this dimmer to use in a new travel trailer. The dinette has 4 LED puck style lights in the ceiling over it which are too bright at times. The wiring instructions are helpful and installation should be simple if you understand 12v wiring and making proper connections. In my case the original on/off switch had only positive wires connected to it so I had connect a negative wire to the nearest light (all the lights have both positive and negative wires) and pull it back to the dimmer switch. This is a good quality dimmer that works smoothly with no flickering. Really happy with it! Supper with nice low lighting is way more enjoyable.

すいませんレビューではなく質問です
ダウンライトの電気の取り方をシガーのオスにしています。 ポータブル電源のシガーメスに刺すと正常に調光できるのですが、サブバッテリーからとっているシガーメスに刺すと一切調光出来なくつきっぱなしになってしまいます。 なぜなのでしょうか?

Great dimmer!
We have two dimmers like this in our camper van that we use with our LED puck lights (same brand). Works great, dimmer works well. I've had other brands in the past that caused the lights to flicker on lower setting, but this one doesn't do this. Works great. Love that it is small and not too apparent in the camper.
