2000 Nissan Maxima HID Kit

I have a 6000K K2 H4 hid conversion kit for my car. I am looking to trade for the same kit but 4200K bulbs. Just the bulbs. They have been in my car for 3 months, and I have not even used them to much, because the car stays at home while i am at school. I will trade straight up for the 4200K bulbs.
