Make all lights stay off
I want to make some kind of switch that can turn on and off all existing and nonexisting lights in a car. Taillights, headlights, interior lights, engine compartment, trunk, LEDs, dashboard, glove compartment. Everything. When the switch is off no light has to be on. When the switch is on all lights need to be back to normal in functioning order. My knowledge of electrical cicuits is limited though I made cicuits long ago. Even though I know some things the electrical system in a car is not to be ****ed around with but I have to do this. I need to do this on my own and I cant go to someone who is certified to do this even though I am willing to invest the money that I got and don't got to make it work. Anybody have any info on how I can do this? Anything at all is appreciated.
