Very Noob Question but ...

Are HID's stock on these? My low beams are blue-ish in colour with bright white hi beams.

I want to get an 8000k HID set Hi/Low for my car and want to have it like the new Accord Euros/BMW's etc -- Projector style. Is this an entire replacement of the Headlight unit or a modification?

Also there seem to be plenty of different ones around - What is a quality brand?

Any help appreciated. Thanks.
