Review on 🔌 American Technology Components 12 Volt DC Dimmer Switch: Ideal for LED, Halogen, Incandescent Lighting in RVs, Autos, Trucks, Marine, and Strips (Large Slider, White) by Travis Caminiti

is needed to dim the built in LED strip under my carport canopy. It worked well, was easy to install and now I no longer glow in the dark when standing under a canopy! A few useful notes: This is a HIGH SIDE PMW (Pulse Width Modulation) dimmer, meaning it will switch +12VDC to light. . You need neutral for this to work. My original switch only had two wires connected: +12VDC to the switch and +12VDC to the LED lights. I connected the RED wire to +12V DC going to the old switch because it was always hot wire, I connected the WHITE wire to +12V DC coming from the old switch because it goes to the LED lights went. I then connected the BLACK wire to the group of neutral wires that were next to my switch. Now I can dim the canopy LEDs!
