Cruising along the UK coast or heading offshore, understanding boat navigation lights is essential for safety and legal compliance. Navigation lights aren’t just a maritime tradition - they help prevent collisions and ensure other vessels can see your boat in low-light conditions. This guide covers everything from the types of lights you need to their colours, meaning, and modern LED options.
What Are Navigation Lights for Boats?
Navigation lights are lights installed on vessels to indicate the size, type, and direction of travel. They help other mariners identify your boat’s position and movement at night or in poor visibility conditions. Using the correct lights is required by law under the International Regulations for Preventing Collisions at Sea (COLREGS).
Boats of all sizes, from small leisure craft to large yachts, need navigation lights that are properly maintained and visible at all times after sunset or during restricted visibility.

Types of Boat Navigation Lights
1. Bow Lights
Bow lights indicate your boat’s direction. Typically, these are red and green lights:
-
Red navigation light – indicates the port (left) side of the boat
-
Green navigation light – indicates the starboard (right) side of the boat
These lights allow other vessels to determine your orientation and avoid collisions.
2. Stern Light
The stern light is white and visible from behind your boat. It lets others know a vessel is moving away from them.
3. Masthead or All-Round Lights
-
All-round white light: Often used on sailboats under 12 metres or as a replacement for separate stern/masthead lights on smaller boats.
-
Masthead light: Usually white, mounted forward, and visible to other vessels from ahead and sides.
4. Special Purpose Lights
Some vessels, like yachts at anchor, fishing boats, or towing vessels, require additional or specific lights to signal their activity.

LED Navigation Lights for Modern Boats
LED boat lights navigation have become increasingly popular because they:
-
Consume less power
-
Last longer than traditional incandescent bulbs
-
Provide brighter, clearer light for safer navigation
Brands like Aqua Signal, Attwood, Hella, Lalizas, and Talamex offer reliable LED navigation lights for boats and yachts.
Colours and Meanings of Boat Navigation Lights
Understanding light colours is crucial:
-
Red light (port side) – indicates the left side of the boat
-
Green light (starboard side) – indicates the right side of the boat
-
White light – stern, anchor, or all-round depending on placement
What do red and green navigation lights mean?
Seeing a red light on another vessel means you are approaching its left side; green means you are approaching its right side. Knowing this helps you manoeuvre safely and avoid collisions.
