Navigating a boat safely at night requires proper lighting to ensure visibility and adherence to maritime regulations. Navigation Signal Lights, also known as boat Navigation Signal Lights, play a crucial role in preventing collisions by indicating a vessel’s position, direction, and activity. As a professional marine lighting manufacturer with 15 years of experience in producing high-quality Navigation Signal Lights, we understand the critical role proper lighting plays in maritime safety， This article explores the types of boat Navigation Signal Lights, their configurations, and why they are essential for nighttime boating.
Navigation lights serve two key purposes:
1. Visibility – They make your boat detectable in darkness, fog, or heavy rain.
2. Communication – They signal your vessel’s size, movement, and status (e.g., anchored, sailing, or towing).
International maritime laws, such as the COLREGs (International Regulations for Preventing Collisions at Sea), require boats to display the correct Navigation Signal Lights to avoid accidents.
Different vessels require specific lighting setups. Here are the primary navigation lights:
Port (Left Side) – Red light, visible from dead ahead to 112.5° to the side.
Starboard (Right Side) – Green light, visible from dead ahead to These lights help other boaters determine your direction and avoid head-on collisions.
A white light at the rear (stern), visible across 135°;Shows your boat’s position to vessels approaching from behind.
A white light at the bow, visible across 225° (from dead ahead to 22.5° behind the beam); Required for motorized boats over 12 meters (39.4 feet) in length.
A 360° white light is used as an anchor light or for smaller boats without a separate stern light.
Towing Light (Yellow) – Indicates a vessel is towing another.
Flashing Lights (Blue/Yellow) – Used by law enforcement or emergency boats; Fishing Lights (Red over White or Green over White) – Signals fishing operations.
| Vessel Type | Required Navigation Signal Lights |
| Powerboat (Underway) | Red (port), green (starboard), stern (white), masthead (if over 12m) |
| Sailboat (Underway) | Red, green, stern light (or tricolor mast light) |
| Anchored Boat | All-round white light (360° visibility) |
| Fishing Vessel | Red over white or green over white |
| Tugboat/Towing Vessel | Masthead light(s), yellow towing light, stern light |
At night, boats must display navigation lights to indicate their position, direction, and status. These typically include a red port (left) light, a green starboard (right) light, a white stern light, and a white masthead light for motorized vessels. Sailboats may show tricolor lights or separate sidelights, while anchored boats display an all-around white light. Specific configurations vary based on vessel size, type, and activity
