Re: Anchor light
Do not neglect your masthead light. That said, while cruising we used various cheap solar led lights down low. They did not last long at first with salt water finding a way into the works. We eventually ended up putting them into clear plastic screw top containers. If I remember right we used empty peanut butter jars. They recharged just fine and were corrosion free for months. When we were really worried about night time traffic we also hung a bright 12v led bulb mounted in a caged industrial light fixture from the boom. The fixture plugged into a 12v outlet in the cockpit.
