  Mast Head Obstruction Light Assembly
  The Mast Head Obstruction Light is mounted as high up the mast as possible to identify the obstruction to any approaching pilot. Utilising LED light sources for low maintenance and long life, the NVIS red signal (compliant for use with Night Vision Goggles as defined in STANAG1445) is visible at a minimum distance of 6Nm from the ship on a clear dark night through 360 degrees of azimuth.

The Mast Head Obstruction Light has 3 basic roles:
  • Occulting, with a variable exposure of light up to 3 minutes in duration to assist the helicopter pilot to identify its ship.
  • Flashing, at a rate of 30 flashes per minute for use during ASW.
  • Solid colour, to illuminate the mast head as an obstruction.
The Mast Head Obstruction Light can be combined with the Homing Beacon to provide a dual function light.
