What is the key distinguishing feature of an intermittent light?

An intermittent light is specifically designed to turn on and off at set intervals, creating a pattern that can be easily recognized by observers. This feature distinguishes it from other types of lights that may remain constant, have variable brightness, or flash in a manner that does not follow a predictable rhythm. The consistent on/off cycle of an intermittent light allows it to serve vital functions, such as signaling to vessels for navigation or safety purposes. Understanding this characteristic is key for anyone operating within marine environments, as recognizing different light patterns can be crucial for safe navigation.
