The previous owner of my car put in a HID kit w/ 10000K bulbs. These are too wayy too purple for my taste and provide little to no visibility-my foglights are actually brighter.

If I was going to want to put in something like 4-6000k would I have to get a new HID kit, or could I simply buy new bulbs.

If I can buy new HID bulbs, what is a good site online where I could purchase a bulb around the 4-7500K mark.
