S.D. Admin. R. 41:04:05:18
From sunset to sunrise in all weathers, the operator of a boat shall exhibit lights as required in Inland Rules 20 through 30, and Annex I--Positioning and Technical Details of Lights and Shapes, and Annex II--Additional Signals for Fishing Vessels Fishing in Close Proximity, as published by the United States Coast Guard in "Navigation Rules, International--Inland." In lieu of meeting the requirements of the inland rules, a boat may meet the requirements of International Rules 20 through 30, and Annex I and Annex II as published in the same document. However, the requirements of this section do not apply to a law enforcement officer, as defined in §23-3-27, while operating a boat owned, leased, or otherwise the property of the state or a political subdivision, in the performance of the officer's law enforcement duties if the officer's conduct is reasonable and if the officer reasonably believes that operating the boat without lights is necessary under the circumstances to investigate a criminal violation or suspected criminal violation of state laws or rules, court orders, or municipal or county ordinances. A law enforcement officer may not operate a boat without lights under this section:
