Imagine my disappointment when I installed the light (after an eleven-hour round-trip to Tucson to pick it up) to learn that it emitted RED light! The company I ordered it from apologized and sent a replacement. After another trip to Tucson to pick it up, imagine my continued disappointment to learn that the new light has a different mount AND it does not have the automatic on\/off feature. A call to the company confirmed that the lamp they sent me is all that they have. Since I am restepping the mast in a couple of days, I did not have time to arrange for a new light, but I really wanted the automatic on\/off feature. So &#8230; I ordered a small circuit board from Amazon (with one-day service) that is designed to turn automobile headlights on automatically at night. Naturally, the circuit board came with ZERO instructions. Here I am doing a quick test of the circuit using my car battery to confirm that it works.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"525\" height=\"394\" src=\"https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2022\/09\/IMG_5984.jpg?resize=525%2C394&#038;ssl=1\" alt=\"\" class=\"wp-image-441\" srcset=\"https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2022\/09\/IMG_5984.jpg?w=1000&amp;ssl=1 1000w, https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2022\/09\/IMG_5984.jpg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/aegir-ran.com\/wp-content\/uploads\/2022\/09\/IMG_5984.jpg?resize=768%2C576&amp;ssl=1 768w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The white wire in the lower left had the photodiode at the end (covered with black electrical tape). A few tests demonstrated the relay on the board can either be configured normally on or off. The first time I wired it backwards (the anchor light was on during the day), but switching a couple of wires fixed the problem.  Since I imagine this add-on would be of interest to other sailors, I will post the details later.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I ordered a new LED anchor light that is supposed to turn on automatically at night.
