- (a) Except as provided in [paragraph (d)](#d) of this section, no person may operate a small unmanned aircraft system at night unless—
  - (1) The remote pilot in command of the small unmanned aircraft has completed an initial knowledge test or training, as applicable, under [§ 107.65](/cfr/14/107.65.md) after April 6, 2021; and
  - (2) The small unmanned aircraft has lighted anti-collision lighting visible for at least 3 statute miles that has a flash rate sufficient to avoid a collision. The remote pilot in command may reduce the intensity of, but may not extinguish, the anti-collision lighting if he or she determines that, because of operating conditions, it would be in the interest of safety to do so.
- (b) No person may operate a small unmanned aircraft system during periods of civil twilight unless the small unmanned aircraft has lighted anti-collision lighting visible for at least 3 statute miles that has a flash rate sufficient to avoid a collision. The remote pilot in command may reduce the intensity of, but may not extinguish, the anti-collision lighting if he or she determines that, because of operating conditions, it would be in the interest of safety to do so.
- (c) **For purposes of paragraph (b) of this section, civil twilight refers to the following—**
  - (1) Except for Alaska, a period of time that begins 30 minutes before official sunrise and ends at official sunrise;
  - (2) Except for Alaska, a period of time that begins at official sunset and ends 30 minutes after official sunset; and
  - (3) **In Alaska, the period of civil twilight as defined in the Air Almanac.**
- (d) After May 17, 2021, no person may operate a small unmanned aircraft system at night in accordance with a certificate of waiver issued prior to April 21, 2021 under [§ 107.200](/cfr/14/107.200.md).
