Navigation Light · Signaling & Visual
Sealite Masthead 3nm-C is a marine Navigation Light within the Signaling & Visual group. Equipment of this type is typically installed at the mast, bridge wing, deck or signaling station where the required light or visual signal has an unobstructed field of view. Its primary duty is visual navigation or signaling duty associated with the Navigation Light, and it depends on the light source, optical housing, power supply, mounting alignment and control or monitoring circuit remaining serviceable. Neighboring variants can differ in rating, size, interface, approval basis or arrangement, so the complete model designation and actual nameplate data are important for identification. It normally interfaces with navigation-light panels or local controls, ship power, cabling, mounting structures and alarm monitoring where fitted.
