What Color Are the Running Lights on a Boat?

Boats are equipped with various lights to ensure safe navigation, especially during low visibility conditions. One of the most important lights on a boat is the running lights.

But what color are these lights? Let’s find out!

Running lights on a boat typically come in three colors: red, green, and white. These colors serve different purposes and help other boaters determine the direction and type of vessel they are encountering.

The port side running light is red, while the starboard side running light is green. These lights are positioned on the left and right sides of the boat, respectively.

They are often referred to as “sidelights” or “navigation lights.” The red light on the port side indicates that the vessel is approaching from your left side, while the green light on the starboard side indicates that the vessel is approaching from your right side.

It’s worth noting that these running lights should be visible from at least 112.5 degrees both forward and aft of their respective sides of the boat. This helps other boaters determine your vessel’s heading and avoid any potential collisions.

In addition to the red and green sidelights, boats also have a white sternlight at the rear. The sternlight illuminates in all directions behind the boat and alerts other boaters that they are approaching from behind.

To recap:

  • Port Side Running Light: Red
  • Starboard Side Running Light: Green
  • Sternlight: White

Now let’s understand when these running lights should be used. According to marine regulations, running lights must be turned on between sunset and sunrise or during periods of limited visibility such as fog or heavy rain. It’s important for all boaters to comply with these regulations to ensure safety on the water.

When operating a boat at night, it is crucial to rely on these running lights to properly navigate and communicate with other vessels. By understanding the color and purpose of each light, you can easily identify the direction and type of boat you encounter.

In conclusion, the running lights on a boat are red, green, and white. The red light is positioned on the port side, the green light on the starboard side, and the white light at the stern.

Remember to use these lights during low visibility conditions or between sunset and sunrise. By adhering to these guidelines, you contribute to a safer boating experience for everyone on the water.
