Q. The life jacket light shall have a source of energy capable of providing luminous intensity of _____ for a period of _____.




The correct answer is B, '75 CD / 8 hrs.' Life jacket lights must have a luminous intensity of at least 75 candela (CD) and must operate for a minimum period of 8 hours. This regulation ensures that individuals wearing life jackets are highly visible in low visibility or nighttime conditions, which is vital for search and rescue operations at sea.

The light helps rescuers identify survivors quickly and reliably in emergencies, improving the chances of successful rescue in challenging conditions.

  • Life jacket lights are crucial for ensuring visibility in an emergency.
  • The light intensity of 75 CD ensures it is visible from a distance.
  • The 6-hour duration is designed to last throughout a typical rescue window.
  • Regulations ensure all life jackets are equipped with lights for safety.
  • The lights are often powered by long-lasting, water-activated batteries.
