By manage them I mean they can be dimmed down if too bright, they can be put on flash at varying speeds if, say, for emergency as the bow and stern blue LED lights
At anchor we have not use them yet, dimmed them and left them on with the bow and stern lights .
We have anchored at Chacala, Mexico for 3-4 nights and Bahia de Jaltemba for one night. While on shore the boat would light up and we could tell which one s\v Elegant'sea was.
They were not obtrusive so we were not lit up to be noticed but only for safety navigation and finding our boat when kayaking\dinghying out..Also in Chacala there is a fair amount of panga fishing traffic by the dinghy landing area or panga fisherman pier and this helps keep us from harms way.
We simply switched them on and then each night they would light up and each morning turn off. No noticeable battery draw. We just left them on for our passage to Bahia de Jaltemba as it was just a day sail then they did their job again. They are working out great. As we are stopped in a marina now we simply switch them off. If our bow was over-hanging the dock we could leave the bow one for a courtesy so people do not eat the bow anchor on their way by the boat.
Now should we put some underwater?!?!?😬
