Re: HID help
Welcome to the garage.
To my understanding you indeed only have to change the bulbs. 5000 K should be the whitest there is. Probably our vendor Xenondepot can help you out.
Changing the bulbs is easy, you have to remove the vertical bolt which holds the light assy in place and then the light assy pops out when you pull on it. Since the HID´s where installed recently, it should pop out without too much force. Then you can change the bulbs and put it all back in.
