Philips Kit bulb for '05 Legacy?

[PaqZa]

First off, hello, this is my first post on UNYSOC although I've been browsing through it the past couple of days.  I am now the owner of a garnet red '05 Legacy GT that, at the moment is stock. However, I want to replace the headlights with the Philips HID set, but dunno what bulb the new lights use. It's pretty easy to find the correct part for the older Legacys and the Imprezas in general but I've had some trouble figuring out the right bulb for my car.

So, what bulb fits the new Legacy? Thanks in advance.
