hey guys, i have an old Bosch HID kit with H1 bulb on it that I used on projectors, since I'm changing my headlight to stock, can I use the same ballast and just change the bulb to h4 or h3???thanks, I' ve searched but it seems no one has the same problem that i have....
you can run an hid bulb in a stock headlight but i wouldnt recommend it. you should really use projectors for any hid bulb
and so long as the ballast tpye matches the bulb type, the new bulb will plug in fine.
