I have HIDs and yes they are illegal, although i have exceptional night vision when they r in use!

Most new model cars now come with HID'S from factory, so really who's to say that they're really illegal?

The way i see it is, if you add modifications to ur car then yes they are defectable no matter what it is, whether u've lowered it, the size of the wheels, the profile of the tyre, exhaust, extractors, CAI, tints.. you name it....

There is no such term as modifying it legally LOL... i doubt anyone does that nowadays, unless the have an engineering certificate to prove otherwise.
