Hi John,
is that a 35W HID kit? Or is it higher rated? Both, a 35W or a higher rated HID kit use more ampere at start up than normal bulbs. Also the HID headlight bulbs must match the ballasts capacity.
did a short search on the wiring myself and found this:

Wow, that's not how it should be wired in general, because Xenon HIDs suck more amperes than standard headlamps, especially when they start up. That's why in general there is an additional relay with an additional fuse that are both adjusted to the higher ampere consumption, especially at the start up of the headlamps.
That means the ballasts are switched by the cars light relay which is switched by the light switch. Additionally there are the headlight fuses of the car.
If the light switch would not work, the headlight would not try to ignite. The headlights are not switched by the headlight switch itself, they are switched by the light relays.
Because of the fact that the headlights try to ignite i would say the ballasts are both gone or you have a wiring problem at the ballasts, or they didn't get enough ampere to start up.
Additional question:
Do the normal headlights work in your car?

PS: the wiring diagrams for ROW, USA and Canada differ a bit when it comes to headlights. Canada for example has additional relays for daytime running lights.
