So I'm trying to wire some interior LED's to my headlight switch so they only come one when the headlights do. I was thinking about just tapping into the fuse but apparently, tech support of the led company said that the fuse will always have 12 volts going to it and thus the led's will too and will be powered. Is this true? If so, I do just want to tap into the headlight switch power wire. Do you guys know where I can access that?

Thanks!
