High Intensity with Appurtenance Obstruction Lights
When a structure lighted by a high intensity
flashing light system is topped with an antenna
or similar appurtenance exceeding 40 feet (12m)
in height, a medium intensity flashing white
light (L-865) should be placed within 40 feet
(12m) from the tip of the appurtenance. This
light should operate 24 hours a day and flash
simultaneously with the rest of the lighting
system.
