12 volt LED not dimming???

Hello All,
I have a 1991 25 ft Excella. I upgraded all the lights to LED and most of them have worked great. My dinette light was upgraded to 6 LED (3 watt bulbs, then I changed them to 2 watt bulbs.....1 total amp, so not a big load). I have tried three different brands/makes of remote control dimmers and they don't work. The light works, and light up by default when the power is on. I have a manual switch that works to turn them on and off. However, my PWM dimmre doesn't do anything. While the lights come on when supplied, the PWMD remote control doesn't dim, brighten, or turn the lights on or off. I'm thinking I did something wrong when I rewired them, but I can't figure it out. Any suggestions would be greatly appreciated!
Regards,
Jeff

Not all LEDs are dimmable.
Were yours sold as such?

I had some that would flicker, then shutoff.

Both are correct. The first bulbs were not dimmable, but I would have been okay if the on/off switch had worked (it didn't). The second bulbs were dimmabke, but still didn't work either dimming or on/off so I have to think something is funky with my wiring job.

They might be polarity sensitive, switch the positive and negative.

Yup... reverse polarity. I flipped my wires and it works perfectly. Thanks all!
