An Air traffic obstacle is a tall structure which can endanger air traffic. Air traffic obstacles have to be marked in most cases with red and white colored markings and with aircraft warning lights at night. On larger structures blinking lights are required.
In the past lamps similar to those used on lighthouses were sometimes used. There are still such lamps on Fernsehturm Stuttgart in Stuttgart, Germany.
A special method of marking was used at the mast of Deutschlandsender Herzberg/Elster in 1939. Its lense-like top was lit by rotating skybeamers. Because of this no electrical installation was required on this mast, which showed as insulated mast radator a high voltage against ground.
