I don't know about others, but the slight yellow tint of halogens helps me with contrast at night. Too white and I feel like contrast suffers. ~4300k was my typical HID preference IIRC (on my motorcycles).
The best thing I ever did for driving at night was getting my glasses with a slight amber tint, it really makes things "pop" at night.
