What colors represent side lights on vessels?

The side lights on vessels are represented by the colors red and green. These colors are used to indicate the direction a vessel is facing and to help prevent collisions between vessels at night or in low visibility conditions. The red light is typically located on the port (left) side of the vessel, while the green light is on the starboard (right) side. This color coding allows other boats to determine the orientation of a vessel and assess the safest way to navigate around it. Understanding and recognizing these colors is essential for all boaters, as it contributes to safe navigation on the water.
