Review on 🔆 Versatile Silver 12 Volt DC Dimmer for LED, Halogen, Incandescent Lights - Ideal for RVs, Autos, Trucks, Boats, and Strip Lighting by Dave Moody

The small form factor is good and the barrel and metal grip look high quality. After you install it, it works perfectly. Two installation problems. First, the wires are incredibly good, I think 24 gauge (my 22 gauge stripper couldn't strip it). This made stripping more difficult, but also made it difficult to get a good crimp. Secondly, the connection instructions on the packaging do not work. Using three separate wires like a traditional switch resulted in the light turning on at a very low level even when it was off. There is an alternative "simplified" schematic on the Revain product page that works - the black wire connects to the plus and the white and red wires to the lamps, there is no ground. It doesn't make sense to me and I hope it's safe - at least the loads are light.
