Differentiate between "working light" and "navigational light."

The distinction between "working light" and "navigational light" is fundamental to understanding their respective purposes aboard a vessel. Working lights are designed to illuminate specific areas where tasks are being performed, such as the deck or loading areas. Their primary function is to provide adequate lighting to ensure safe and efficient operations, allowing crew members to see and carry out their duties effectively.

On the other hand, navigational lights serve a critical role in maritime safety. They are essential for maintaining visibility and signaling a vessel's position and heading to other vessels in the vicinity, especially in low-light conditions. Navigational lights help prevent collisions by indicating the presence and movement of the vessel to others navigating in the same waters.

This distinction underscores the importance of each light type: working lights focus on operational safety and task completion aboard the ship, while navigational lights are vital for the safety of the ship in relation to other watercraft.
