Attenuated Night Vision

[SignedName]

Basically what I'm requesting is night vision similar to that found in Amnesia: The Dark Descent for use with mods that make nights darker. Basically, a weak night vision effect that fades in the longer one is away from an active light source, and which weakens the longer one is near a light source, so that pitch black nights will mean bad things if you're stepping out of a brightly-lit room into the wastes, but will be less of a problem if you take a few minutes to attenuate yourself to the darkness.
