Review on 🔵 ESUPPORT 12V Momentary Car Vehicle Blue LED Light Headlight Push Button Metal Toggle Switch Socket Plug 19mm Fire Missiles - Ultimate Control for Car Lighting by Skyy Strickland

cooling switch. understood the diagram. I connected the red to the parking lights and the black to the ground so the light was on all the time. Yellow goes to light/horn or whatever you switch. And if you want the light to turn on when the switch is pressed, connect the green to power and connect the red and blue together. Still black to ground and yellow to whatever your switch is.
