running light
Vessel position indicator
A running light is a light displayed on a vehicle or vessel to indicate its presence and position, especially at night.
Ships carry running lights in specific configurations—red on port, green on starboard, white at stern—so other vessels can determine their heading.
Cars, trucks, and aircraft also have running lights that remain on during operation.
The boat's running lights were visible across the dark harbor.
