Key International Regulations for Marine Lighting

These regulations are designed to standardize marine lighting systems across vessels and maritime installations, ensuring visibility and operational safety at sea.

1. International Maritime Organization (IMO)

The IMO, a specialized agency of the United Nations, establishes global standards for the safety, security, and environmental performance of international shipping.

a. International Regulations for Preventing Collisions at Sea (COLREGs)

COLREGs, also known as the Rules of the Road, define color and visibility requirements for navigation lights.

Key provisions include:

  • Color Coding: Red for port (left), green for starboard (right), and white for stern or masthead.
  • Visibility Range: Lights must be visible from 2 to 6 nautical miles, depending on the vessel’s size and type.
  • Placement: Lights must be positioned to indicate the vessel’s size, direction, and status (e.g., underway, anchored).

  • ABYC A-16: Focuses on navigation lights for small craft, detailing installation practices to meet visibility and reliability criteria.

2. European Standards

a. EN Standards


European standards, established by the European Committee for Standardization (CEN), provide comprehensive guidelines for marine lighting.

  • EN 14744: Specifies requirements for navigation lights, including color, intensity, and visibility ranges to ensure compliance across European waterways.
  • Energy Efficiency: Emphasizes energy-saving technologies like LEDs to align with the EU’s sustainability goals.

b. Classification Societies


Organizations like Bureau Veritas, DNV (Det Norske Veritas), and Lloyd’s Register enforce regional rules for marine lighting systems. These societies conduct inspections and issue certifications based on compliance with their specific standards.

3. Asian Standards

a. China Classification Society (CCS)

  • CCS sets technical standards for lighting systems on ships registered in China.
  • Focus areas include durability, compliance with COLREGs, and integration with modern energy-efficient technologies.

b. Japanese Industrial Standards (JIS)

JIS provides guidelines for marine lighting in Japanese waters, emphasizing high performance and resistance to environmental factors like typhoons and seismic activity.

4. Australian Standards

a. Australian Maritime Safety Authority (AMSA)


AMSA aligns with IMO guidelines but includes additional requirements tailored for Australian waters.

Navigation lights must be robust enough to handle harsh marine conditions, such as strong winds and high UV exposure.

b. National Standard for Commercial Vessels (NSCV)

Part C of the NSCV details specific lighting requirements for commercial vessels, ensuring visibility and safety in Australia’s unique maritime environment.

5. Canadian Standards

a. Transport Canada


Transport Canada enforces marine lighting requirements in alignment with international standards, with added provisions for operations in Arctic and inland waters.

Navigation lights for icebreakers and polar vessels are designed to withstand extreme cold and prolonged darkness.
