Required Lights: Power-Driven Vessels When Underway
If less than 26 feet long, the required lights for power-driven vessels are:
- Red and green sidelights visible from a distance of at least one mile away.
- An all-round white light or both a masthead light and a sternlight. These lights must be visible from a distance of at least two miles away. The all-round white light (or the masthead light) must be higher than the sidelights.
