I don't think this was mentioned but I would include a good, very bright flashlight such as a Streamlight Ultrastinger, Tigerlight FBOP, or as last resort, a Magcharger. In my experience in urban and rural environments there is never enough light to go around at night. Also, its easier to see street numbers that are set off the road with a good flashlight than using floods or alley lights.

A good trick is that if you are shorthanded you can stick the light in your back pocket and aim it at the ceiling. There will be enough reflected light for an inital assessment or to carry a patient down stairs.
