There are many types of marine lighting fixtures, mainly including the following categories:
Navigation lights: used to display the direction and size of a ship's navigation at night, including mast lights, side lights, taillights, etc. The mast light is a white light placed above the centerline of the bow and stern of the ship, the side lights include a green light on the starboard side and a red light on the port side, and the tail lights are white lights placed as close to the stern as possible. The color and location of these lighting fixtures are strictly regulated to ensure that the vessel can be clearly identified by other vessels at night or in low visibility conditions.
Signal lights: used to transmit specific information or instructions, including ambient lights, ambient yellow flashing lights, control signal lights, etc. The ambient light displays uninterrupted light within a 360 degree horizontal arc, while the ambient yellow flash provides additional warning function.
Emergency lighting: put into use when the main power grid fails, ensuring that the ship can still provide necessary lighting in emergency situations. The emergency lighting system is mainly distributed in important areas of the engine room, crew and passenger cabins, etc., and is required to maintain at least 3 hours of illumination.
Searchlight: Used for searching the water surface or other situations that require strong light illumination, providing long-range illumination.
Other special lighting fixtures: Depending on the specific needs and operations of the vessel, other types of lighting fixtures such as anchor lights, tow lights, etc. may also be used to meet specific navigation or safety requirements.
