I have mine wired to my running lights and then channelled through a toggle switch. I had blue ones which looked great but then i had some wiring problems and now i have green ones. Unfortunately i am having the same problem with the wire connecting directly to the nozzle. The solid part where it is saudered i believe. I would not recommend getting caught with them though, in Washington its 86 bucks each time.
