Definition of Navigation Lights
Navigation lights are the lights used on boats and ships to help indicate their position and movement in order to prevent collisions and ensure safe navigation.
There are six types of navigation lights:
- Stern Light: White light at the stern (rear)
- Port Light: Red light on the port (left) side
- Starboard Light: Green light on the starboard (right) side
- Towing Light: Yellow light used on vessels towing other vessels
- All-Round Light: White light used on vessels under 23 feet long to show their position while underway and at anchor.
- Masthead Light: White light placed on the masthead of a boat, required for vessels over 39.4 feet in length
Here’s a table detailing the regulatory requirements for each type of navigation light.
Navigation Light Type | Color | Location | Visibility Distance | Visibility Angle |
Port light | Red | Port | 1 nautical mile | 112.5 degrees |
Starboard light | Green | Starboard | 1 nautical mile | 112.5 degrees |
Stern light | White | Stern | 2 nautical miles | 135 degrees |
Masthead light | White | Masthead | 3 nautical miles | 225 degrees |
Towing light | Yellow | Stern and masthead | 2 nautical miles | 135 degrees |
All-Round light | White | At or near the center of the vessel | 2 nautical miles | 360 degrees |
Since COLREGS regulations require navigation lights to be on from sunset to sunrise and in low visibility conditions, finding an energy efficient light solution will save you time and battery juice.
LED lights are top of the class when it comes to conserving energy while delivering on brightness.
