Hope this is the right area to post this, but I was looking around on hid planet and found a thread with this link.

I have no affiliation, just passing on a GREAT deal. These are $150 a piece at the dealer and these are the + version(doesn't color shift as fast, stays whiter longer).

I thought I would share it here since some of our cars are getting on in age and HID bulbs slowly loose there brightness over time. The hid's on my s2000 are pretty dim and hardly look any better than my subaru's reflector hids.

 

actually, 85122+ bulbs are more yellow

as a bulb color shifts, it turns whiter with usage
