I’ve got a HID kit which I fitted to my car to test, but doesn’t work correctly with the particular setup of my MK2 (If you have both side and dipped beam on a single bulb, then they won’t work for you either.)
They were marked up as 4300k (apparently this is similar to OEM installations), though I think they are slightly whiter and maybe the 5000k and are the brighter 55w kit.
The kit is plug’n’play and has everything you need, though I might suggest something other than the provided double-sided tape to secure the ballast.
I know this is for sale, but I’m pretty much open to any offer. If you are going to JAE, then I will bring them along.
