Final answer:
The range of visibility for a towing light is typically 2 nautical miles for smaller vessels. This is important for safety and visibility at sea.
Step-by-step explanation:
The range of visibility for a towing light, as regulated by international maritime law, is typically 2 nautical miles for a vessel less than 12 meters in length. This specification is crucial to ensure visibility and safety during towing operations at sea, especially in conditions with limited visibility. Note that the actual visibility range can be influenced by factors like weather conditions, the height of the light above sea level, and the observer's height of eye.
