One of the features of my M class that I've become addicted to are the BiXenon headlights - they provide a nice crisp cutoff without any glare to the other drivers. Are there any worthwhile HID conversion kits available for the Prius? I'm not looking for any of the silly Xenon-look bulbs that are tinted blue or, even worse, purple so they provide less light output than the stock bulbs. Ideally I'd like a full projector housing replacement running around 4500 Kelvins that will allow me to keep the high beams, but any upgrade that won't just scatter the light into the oncoming traffic would be worth looking into.
