XentecH1 6000K HID xenon bulb x 1 pair bundle with 2 x 35W Digital Slim Ballast (Ultra White)

My ballast died. How can i get a new one?

Would this fit any car the used h1 and h7?

I installed on my 2012 Dodge Charger and they work perfect with the car off but when engine on the lights flicker then shut off, what is needed ?

Why would this i le be working when I turn my pick up off, when I turn the pickup on they shut off??
