    In years past, temporary construction lighting was no more than a modified OB1 side marker once the structure reached 200'. Today, the FAA is fining, when observed, tower owners, not the erector, for violating the Obstruction Lights During Construction standards in FAA AC-70/7460-1K. In part, the advisory states: As the height of the structure exceeds each level at which permanent obstruction lights would be recommended, two or more lights of the type specified in the determination should be installed at that level. Temporary high or medium intensity flashing white lights, as recommended in the determination, should be operated 24 hours a day until all permanent lights are in operation.
