Sec. 67.05-10  Characteristics of obstruction lights.



    All obstruction lights required by this part shall be powered from a 

reliable power source, including auxiliary power sources as necessary. 

They shall display a quick-flash characteristic of approximately 60 

flashes per minute, unless prescribed otherwise in the permit issued by 

the District Commander. Their color shall be white when marking Class 

``A'' and ``B'' structures, and either white or red, as prescribed by 

the District Commander, when marking Class ``C'' structures. In 

determining whether white or red lights shall be authorized, the 

District Commander shall take into consideration matters concerning, but 

not necessarily limited to, the dimensions of the structure and the 

depth of water in which it is located; the proximity of the structure to 

vessel routes; the nature and amount of vessel traffic; and the effect 

of background lighting.
