Xenons burn at around 5000K while standard halogens burn at around 3200K. Both 'white', just that 5000K appears more blue and 3200K more yellow. Ever take a picture inside (with incandescent lighting,) with daylight film and no flash. The resulting picture looks yellow. This is because daylight film is balance for 5000K, (sunlight, photo flash) while incandescent lighting is around 3200K.

I don't know about the emergency vehicle part, but I do know that it is illegal in NJ to have any foward facing lights that aren't clear or yellow.

It is also true that blue filters, may they be dyed glass on the bulb, or on the headlight screen, reduce the amount of usable light reaching the road.
