Is that the car in the pic?
I can't see any headlight washers on the bumper, are you sure it has factory Xenon's?
It certainly has projector dipped beams, in which case it will be an H7 bulb.
If it does have factory Xenon's, then it should be a D2s bulb.
if it's an aftermarket HID kit fitted, then H7 seated capsules should be available easily and fit most HID kits.
