The flash rate of a special flashing light is established at 120 flashes per minute. This specification is critical as it ensures the light is easily recognizable and discernible from other maritime lighting. The consistent rate of 120 flashes per minute provides a standardized signal that can be universally understood by mariners, improving safety and communication on the water. While it is true that different states may have their own regulations regarding lighting, the standard flash rate is not subject to variation based on state rules but is instead defined for specific applications, particularly in contexts like navigation and safety signals. The purpose of maintaining a specific flash rate is to provide uniformity in signaling that enhances awareness and recognition among operators of vessels.
