What should you do to activate the light on a life vest?

• A. Inflate it manually
• B. Automatically upon entering water
• C. Pull the inflation tab
• D. Press a button on the vest

Answer: (B)

To activate the light on a life vest, it typically operates automatically upon entering the water. This automatic activation is designed to enhance visibility in emergency situations, especially when a person is submerged or in distress at sea.

The life vest is equipped with a water-sensitive mechanism that triggers the light once it detects contact with water. This ensures that the light is activated at the right moment, without requiring the wearer to take extra steps, allowing for immediate signaling to rescuers.

Options involving manual inflation or pulling a tab are related to different functions of the life vest, such as inflating the vest itself. These actions do not contribute to the functioning of the light. Similarly, pressing a button or manually activating the light is not a standard feature in many life vests, as the automatic activation is preferred for quick response during emergencies.
