Navigation Light Rules
- Port sidelights are red, starboard sidelights are green and both shine from dead ahead to 112.5° aft on either side.
- Stern lights are white and shine aft and 67.5° forward on each side.
- All-round lights are white and shine through 360°.
These lights provide critical information to the operators of other vessels when they see you. Other vessels around you make collision avoidance decisions based on the information available to them, that’s why it is so important that the information your navigation lights are giving them is the correct information.
In general, LED lights for navigation lights are fine but they must meet Coast Guard requirements and approval. (This statement is not specific to LED strip lights but LED lights in general). Manufacturer installed navigation lights should be considered to meet the requirements.
Is starboard a red port?
Red lights are located portside, and green are starboard. The lights shine from dead ahead to 112.5º aft on either side of the vessel. On some boats, sidelights can be combined into one bicolor light.
