The Homing Beacon Light is mounted as high up the mast, or cross arm, as possible to identify the vessel to any approaching pilot. Utilising LED light sources for low maintenance and long life, the NVIS occulting white or red signal (compliant for use with Night Vision Devices as defined in STANAG 1445 & DEFSTAN 02-587 part 3) is visible up to 3km, subject to prevailing night time conditions. The occulting can be varied so that light exposure can be up to 3 minutes in duration. The Homing Beacon can be combined with the Mast Head Obstruction Light to provide a dual purpose fitting.
