What distinguishes a quick flashing light from a regular flashing light?

A quick flashing light is characterized by a higher frequency of flashes compared to a regular flashing light. This means that the intervals between each flash are shorter, allowing for more flashes to be seen in a given amount of time. The primary purpose of this differentiation lies in navigational aids, where quick flashing lights can serve to grab the attention of mariners more effectively than regular flashing lights.

The designations for light characteristics—such as quick flashing—are important for giving specific information about the position or nature of navigational hazards, channel markers, or other critical reference points for vessels. The rapid rate of flashes helps to convey urgency and enhances visibility during periods of low light or poor weather conditions. Understanding these nuances aids mariners in making informed decisions while navigating waterways.
