I thought about the battery powered ones myself as I have only been out a couple of times at twilight rushing back to the dock. Then I remembered battery powered means batteries and the chances of the batteries being at full charge is not very good. Best bet for "me" was to use plug in lights with a wind up cord. So that is what I made. I will plug them in if I ever need them, and don't have to worry about testing them the rest of the time. No dead batteries at the wrong time, and less long term cost. Plus C-cell batteries likely to leak acid destroying the "flashlight" nav light.
