I think the ability to have a good amount of light available if you need it is really nice, like led light strips, though I don’t normally go that far, plenty of times I wish I would’ve.
Organization I think is key like the others said, minimal stuff, well organized.
A flashlight on the net is nice too, so you can see your catch comming in.

I’d also like to mention, that you need to be extra careful out there on the water, for so many reasons, though against the law, I’ve seen and heard of plenty of stories about boats on the lake at night without any lights on , no anchor light nothing. Bouy’s are pretty darn hard to see too. I have 2 spotlights in my boat at all times, 1 is a 5 millon candlepower spotlight the other is a 1 millon candle power spotlight I keep as a back up, or sometimes when I don’t want to light up the world. ( which reminds me my 1 millon isn’t working properly Found that out on the water when I needed it of course I had the big one to back me up, would’ve been a really long drive back otherwise. )
Secondly there has been more than a couple incidents where people have hit rocks and reefs at night going by GPS navigation. Be aware GPS are not flawless, even if it shows you are on the exact trail you ran earlier doesn’t mean you are exactly where is says, People hit stuff at night all the time going by GPS navigation, lake contour maps are far from accurate in most cases I can say all bets are off in shallow water. Use extreme caution. Not to mention if you are staring at the GPS all the time you may not be paying enough attention to where you are going, anchor lights (providing they are on, aren’t always the easiest to see.)
Drive slow, I Only go as fast as I need to get on plain, in my boat I’m doing around 30 mph, that’s a bit hairy in my book, so I don’t try and night fish water I don’t know, or I’m stuck at 6 mph max. (obviously my boat could benefit from some prop and motor adjustment )
I’m an old boyscout I come prepared , extra batteries, power cords to plug in my spot lights if need be, jumper cables and or portable jumper. Or course that stuff is packed away neatly, but I have it if I need it.
Not a bad idea either to give some one a “Float plan” where you intend to go, where you may go, when you leave and when you intend to be back. US coast guard I believe has a nice little sheet you can fill out. Not to say I’ve done anything like that a lot, but really is a easy and very good suggestion.
