A masthead light is a white light located at the highest point of a vessel, typically on the mast or superstructure. It helps other vessels identify the boat's presence, direction of travel, and size when navigating in low visibility conditions. The masthead light is required by maritime regulations, especially at night or in restricted visibility.
Charles F. Brush invented the arc light to provide brighter and more efficient lighting for street lamps and other outdoor lighting applications. His invention helped to improve visibility and safety in cities during nighttime.
Light reflection material enhances visibility in low-light conditions by reflecting light back towards its source, making the wearer or object more visible to others. This increased visibility helps to improve safety and reduce the risk of accidents in situations where visibility is limited.
Light has different meanings, so the opposite could be heavy or it could be dark.
Dust particles in light can create unwanted spots or blurs in photographs, reducing visibility and overall quality.

The masthead light should be visible in a 225 degree arc centered on dead ahead.
A masthead light on a boat is a navigational light mounted at the highest point of the vessel's mast. It illuminates white light and is visible from all directions, serving to indicate the boat's presence to other vessels, particularly when under sail or at anchor. The masthead light is crucial for safety, ensuring compliance with maritime regulations and helping to prevent collisions at night or in low visibility conditions.
The masthead light on a vessel should be visible from the front and sides, specifically from 22.5 degrees on either side of the bow, extending to the stern. This light is white and must be displayed from sunset to sunrise, ensuring that other vessels can see your boat's heading and position. Proper visibility of the masthead light is crucial for safe navigation and collision avoidance at night.
Rules of the Road Lights & Shapes, Rule 21-International Definitions (a) "Masthead light" means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from the right ahead to 22.5 degrees abaft the beam on either side of the vessel.
Rule 21 It must show an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft of the beam.
The masthead light is typically white in color. It is displayed at the top of a vessel to indicate the presence of another vessel at night.
Yes, it is.
A white masthead light must be shown when a powerboat is operating at night.
When underway, a power-driven vessel displays a combination of navigation lights: a white masthead light at the front, sidelights (green on the starboard side and red on the port side), and a white stern light at the rear. The masthead light is visible from ahead and extends 225 degrees, while the sidelights are visible from the side and ahead. The stern light provides visibility from behind. These lights help ensure the vessel is seen and identified by other vessels during nighttime or low visibility conditions.
Rule 21 of the Navigational Rules of the Road. (a) "Masthead light" Means a white light placed over the fore and aft center-line of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed to show the light from right ahead to 22.5 degrees abaft of the beam on either side of the vessel, except that on a vessel of less than 12 meters (39'4") in length the masthead light shall be placed as nearly as practical to the fore and aft center-line of the vessel.
A power-driven vessel of less than 12 meters in length may show an all-round white light in lieu of the masthead light and sternlight. This all-round white light must be visible from all directions and is typically mounted at a height that ensures visibility. Additionally, the vessel may also display sidelights if it is engaged in activities requiring them.
