There is currently a group buy being set up to try to get 25% off a Retroquick HID kit. I found 1 member who did this about a year and a half ago, and seems to have vanished.

Here is a link to the group buy for anyone who is interested.
Has anyone else installed a TRS bi-xenon kit including retrofitting HID projectors?
