dimmer switch for factory LED

does anyone make a dimmer that would work with factory LED lights on our 320 BHDS?

The mirror over the kitchen island has LED strips that run around and provide a great amount of light. The switch is a nice large almost residential feel flip switch, one of two for the ceiling mounted LED lights.

It occurred to me that if dimmed, it would make the perfect night lighting, just enough for the kids to find their way to the bathroom without problem.

LED's are not usually able to be dimmed due to specific power in = light

good point. had not really thought through that, would need to be a PWM dimmer in order to dim the LED strips. I doubt they use a specific driver for the LED strips as they are running 12v DC. Which makes me wonder if there are 12DC PWM dimmers...

They make LED dimmers, but they are not cheap. Just Google it.

The bulbs also need to be dimmable adding to the cost

The bulbs in the RV run off 12v and do not have there own driver circuit so they are all dimmable unlike household bulbs that have a driver circuit built in.You will need a PWM driver ( they will dim down if the voltage is dropped but a PWM driver is better). If you are into electronics there are designs on line for making drives and the parts are cheap.

Don't know what LEDs the factory uses in a 320 BHDS. Most LED bulbs are simple devices and will dim with a simple series current limiting resistor. I replaced all the interior bulbs on my 2012 Solera with LED bulbs from Amazon. On two sets of bulbs - over the bed and over the dinette - I then devised a simple two stage dimmer - (double throw switch which switches a resistor in series with the LED lights in one position). Have camped with the LEDs several weeks now - mostly without hookups - nice and easy on the batteries; very acceptable light. Very low current draw when only using the "dimmed" bulbs; <200 ma for both sets of lights. Found the double throw center off switches at Camping World (they fit in the original switch plate); used five watt resistors (120 ohm if I remember right). Also, this simple resistor dimmer causes NO RF noise.

here is what I was thinking, PWM and realtively inexpensive:
PWM LED Light Bulb Dimmer Brightness Control Wall Switch DC 12V 24V 8A BTE | eBay

not sure if this is PWM, and it is residential size, but it is cool!
DC 12V 24V 8A Channel Touch Panel LED Dimmer for Single Color LED Strip Light | eBay

Thanks for the info, I wasn't aware that you could do this.

Our Columbus 340RK has led lights in the living room area that are on a dimmer. We have had it a month and i noticed that one of the lights isn't dimming right though. I assumed that it was the bulb but i pulled out the fixture and it looks like it is wired direct. Any ideas? the dealer is 50 miles away and i would rather fix it than go that far for someting that minor.
