That Heliduck is the core issue isn't it? The rules here are simple, do not fly at night in a non equipped aircraft. The other discussions about what is and is not NVFR outside a lit up area are very valid and I agree with those sentiments. One of our major EMS operators ban NVFR in less than 1/4 moon condition and those guys are fully IFR equipped.
If we can get them to stop when they should, but how?
