Review on ESUPPORT 16mm 12V 3A Car Purple LED Light Power Metal Push 🚗 Button Toggle Switch Socket Plug Latching Black Shell: Illuminating Control for Automotive Applications by Darrell Shreves

The knob was very easy to install and works great for my application to control some of the LED lights on my truck. I installed it on the dash of my 2003 Yukon Denali and it's wired to control my green strobe lights which I use when answering emergency calls as I volunteer with the local emergency services. I followed a wiring diagram that has a green LED all the time so I can hop in the truck at night and see the button to press.
