Headlamps work great but attract bugs to your face. I use a 10' piece of closet dowel from Home Depot, wrapped about 6' of a white LED strip around one end of it and zip tied it so it won't peel off, then ran a wire down it to a cigarette lighter plug on the end. I drop it in one of my vertical rod holders on the side of the center console and plug it into the 12v outlet at the helm. It lights up my whole boat like a lantern and keeps the bugs well overhead. Also meets the requirements of the anchor light.
If you're not living on the edge, you're taking up too much space!
