Night fishing is a hoot and very productive.
USCG: You are required to carry a light to warn in time to avoid collision or display same lights as a small sail boat and a sound signal like a horn or whistle. A flashing strobe is an emergency signal, it's a good idea to carry one and if you are trouble use it, but reserve it for emergencies.
NYS: You are on yr own regarding any additional state regs usually abv satisfies the state req.
I personally wear a headlamp and carry an air horn where it can be reached easily. Headlamp makes you pretty visible if you shine it on a day-glo paddle blade. I also have a 3D cell mag light, plus a mini mag light and a whistle for redundancy. Carry a compass or GPS as well, if any chance you can get fog bound. Better at night with a buddy or 2, I can get creeped out alone.
