The purpose of a masthead light on a power-driven vessel is to shine forward and to both sides. This light is critical for the visibility of the vessel in nighttime or reduced visibility conditions, ensuring that other vessels can see it from various angles. The masthead light typically has a white color and is positioned high on the vessel, making it easier to spot from a distance.

By shining forward and to the sides, the masthead light increases safety by helping to indicate the vessel's direction and movement to other boats, thus preventing potential collisions. It plays a vital role in ensuring navigational awareness among vessels operating in crowded or dark environments, contributing to safe boating practices.
