so my TT doesn't have bi-xenon which was an optional. I'm looking into purchasing slim digital HID kit and install it myself.
Just wondering what are some reliable HID kit brands out there that you guys know and works well with TTs.
I'm planning of getting 6000k H7 at this point and also thought about just replacing the bulb with sylvania silverstar ultra
which claims to produce -4100k. Let me know what ya guys think?

*btw do you guys know the temperature of stock oem halogen lightbulbs make? and which torx screwdriver i need to take out the headlight?
