How do ships move in the darkness without accidents

Cruisin' the deep blue at night, ever wonder how colossal ships avoid calamitous encounters in the dark? It's not magic, folks. It's all down to the marvel of modern technology and good ol' maritime rules. First off, navigation lights. Red on the left, green on the right, and white at the back and top. These tell other ships not only your position, but also your direction. Next, the radar. Like a bat's sonar, it uses radio waves to detect objects, even in pitch black. And don't forget the Automatic Identification System or AIS, broadcasting data like position, course, and speed to ships around. Lastly, maritime traffic rules, the sea's version of road rules, guiding who has right of way. Ships at night? Not a problem. It's all about lights, technology, and rules, folks."
