I have experience with name brand HIDs and non name brand HIDs.
the non name brand were about 1/3 of the price, but i had problems with them in the cold, and eventually one shit out entirely.
get a name brand kit.
I am glad that you are putting them in AT LEAST in projector housings… though OEM HID projectors will do you better in the long run.
You will have to see what kind of bulb it takes, and get THAT KIND of retrofit kit.
Xenondepot.com has kits that use name brand components.
