What is a Navigation Light? What are navigation lights for boats and yachts and why are they mandatory?

A navigation light is a basic maritime safety equipment that makes boats and yachts visible during night navigation or in low visibility conditions (fog, rain, haze) and informs other mariners of the boat's direction, position and navigation status. This system, which is used to reduce the risk of collision in maritime traffic, is based on color and angle standards determined according to international rules.

Asdenizciden.com, we offer navigation light solutions suitable for different boat types and usage scenarios under a single roof with bow, stern, port, starboard and 360° anchor/anchor light options. The following guide provides practical and clear answers to the questions "What is a navigation light?", "What is it for?" and "Why is it mandatory?".


What do navigation beacons do?

  • Provides visibility: Makes the boat easier to recognize at night and in low visibility.
  • Provides direction: Other boats understand the direction of the boat by looking at the light colors and angles.
  • Prevents collision: Maneuvering decisions are made correctly, reducing the risk of collision.
  • Harbor and channel safety: Increases safety during navigation and berthing in narrow areas.
  • Inspection and regulatory compliance: Equipment complying with the rules does not cause problems in possible controls.

Why are navigation lights compulsory?

Navigation lights are part of a safety standard defined by international regulations to prevent collisions at sea. In short, a navigation light is not an "accessory" but a "mandatory safety equipment". During night navigation, a boat without a proper light will be noticed late by other boats, which means a serious risk to both life and property safety.


Navigation Light Types and Angles

1) Bow / Bow (Silion) Navigation Light - 225°

White light pointing in the front direction of the boat. Boats approaching from the front or from the opposite direction can use this light to detect which way the boat's "head" is facing.

2) Stern / Aft Navigation Light - 135°

It is the white light seen from behind the boat. Boats approaching from behind can more accurately read the boat's stern and track with the stern light.

3) Port (Red) Navigation Light - 112,5°

It represents the left side of the boat and gives a red light. When other boats see the red light, they are seeing the "port" side of the boat.

4) Starboard (Green) Navigation Light - 112,5°

It represents the right side of the boat and gives a green light. The green light indicates "starboard side" to the other boat.

5) 360° Anchor / Anchor Light

Gives 360° visible white light when the boat is at anchor. This light helps the anchored boat to be perceived as "stationary/positioned" by surrounding boats.


LED or Bulb? Which Makes More Sense?

There are two common approaches to navigation lights: LED or bulb systems. The choice should take into account the frequency of use, electrical infrastructure and maintenance habits of the boat.

  • LED navigation light: Characterized by low energy consumption and long life.
  • Bulb system: It offers the advantage of simple construction and quick bulb replacement.

Importance of Installation and Accessories

Correct installation is as critical as the right light. Bracket, pole, fasteners and proper positioning directly affect the visibility and performance of the light.


Conclusion Navigation Lighthouse is the Foundation of Maritime Safety

Navigation lights are a basic standard for safe navigation at sea. Choosing the right light for your boat's length, the way it is used and your navigation scenario is critical for the safety of both you and the boats around you. You can examine different brands and types of navigation lights on denizciden.com and easily determine the most suitable solution for your boat.
