Also for anchor lights I don't have faith in a light at the top of the mast, it is out of the line of sight of boats passing close. So I use an LED lantern hanging on the foredeck, the stern running light, and the steaming light at night. All white lights so they fit for anchoring. I also use a black ball for day shape but most of the other mariners don't have a clue about what it means. Tom Evans SV Tappan Zee San Diego
