People historically used lights to communicate through methods such as signal lamps, beacons, and lanterns. For example, lighthouse beacons signaled maritime navigation, while signal lamps, like the heliograph, transmitted Morse Code over long distances using flashes of light. Additionally, various cultures employed fire beacons on hills or towers to relay messages across vast areas, especially in times of war or emergency. These techniques allowed for efficient and quick communication before the advent of modern technology.
