by default or as an option?

I was at my local Acura dealership the other day to service my Integra and noticed the 05 RSX's headlights... they looked different but I am not sure and didn't asked about them being HID.

HID are kind of a deal breaker for me actually. I have them for my Integra, but since the Integra's light reflectors aren't designed for HID, it doesn't look as good as the HID of a S2000 for instance.
