Does anyone know if the H1 ballast and the 9006 ballast are interchangeable? I retrofitted my headlights awhile ago to mini H1. I reused my old 9006 ballast and paired it with h1 hid bulbs. I used the wiring from the 9006 bulb (the one that has the male and female plug that goes into the car headlight wiring and into the ballast). It works, but I'm looking to buy a new kit as mines are getting old. If I buy an H1 hid kit it will comes with bulbs and ballasts for H1. I was wondering if anybody knows if the H1 ballast will fit for our cars. Or would I have to buy a 9006 ballast and h1 bulbs separately?
