I had a problem with my HID light, after using it for the past 3 month one of the bulb (the passanger side) changes colour to purple similar to that of 6000K, I bought my kit 8000K which should have a blueish white color.
The ballast is made from Hella and I bought the kit from a friend which is not complete (that is if you refer to the Hella website, it is the illegal one), it does not have a complete rellay from the balast, hmmm I am quite fed up bcoz when I bought the kit, one of the bulb is actually broken, so I use one HID bulb only, while I order a replacement for the other one, for that 3 month and It now changes color.
Soooooooo in a desperate need of advice, I pledge someone to come up with a suggestion
Ballast: Hella, which may have been fully or partially damaged by damaged bulb(s).
Bylb: unknown brand and quality
Bulb rebaser: unknown
Wiring harness: missing - may have or will partially damaged headlight switch
If u want this to work 100%, I would suggest return kit to seller and buy a quality kit with known parts from autolamps-online.com
If its too pricey for u, stick with halogen. There is no such thing as cheap high quality HID components.
