Sec. 67.30-5  Obstruction lights.



    (a) The obstruction lights shall be white or red lights as 

prescribed in Subpart 67.05 of this part and shall be of sufficient 

candlepower as to be visible at a distance of at least one nautical mile 

90 percent of the nights of the year. The lights shall be displayed at 

such height, above mean high water, as shall be prescribed by the 

District Commander. When the District Commander shall authorize red

    (b) When Class ``C'' structures are erected in close proximity to 

each other, or are connected in such a manner as to prevent marine 

traffic from passing freely through the field, obstruction lights may be 

authorized to mark the perimeter structures only, when in the judgment 

of the District Commander the group of structures which are equipped 

with obstruction lights are so arranged that the particular structures 

are protected to the degree required by this part, and are not a hazard 

to navigation.

    (c) Unless advised to the contrary by the District Commander, 

obstruction lights shall be required on Class ``C'' structures erected 

in depths of water greater than 3 feet at mean low water.

    (d) In cases where, although not required, an applicant desires to 

establish and operate obstruction lights, a permit therefor shall be 

granted, at the discretion of the District Commander: Provided, That the 

lights meet the requirements set forth in this part.
