I would suggest that you get a good handle on the rips during the day, I mean a good one! You want to know what to expect in various conditions. As Skip said some of the rips....especially the shallower ones can surprise you during the day, let alone during the night.
A float plan left with someone responsible is a great idea. See if you can find another boat to buddy with. Don't go out there at night alone, have a crew. Make sure your lights work and all of your safety equipment is at hand and working, keep life jackets at the ready.
I did a little rips fishing this summer in the dark. There is something unsettling about drifting slowly along......then hearing waves crashing.....and then suddenly getting tossed here and there. We got used to it after a few trips.
