When may a remote pilot reduce the intensity of an aircraft's anti-collision lights during a night flight?
AAt no time may the lights of an sUAS be reduced in intensity at night.
BWhen a manned aircraft is in the vicinity of the sUAS.
CWhen it is in the interest of safety to dim the aircraft's lights.✓
Why →Under 14 CFR § 107.29(a)(2), the remote PIC may reduce the intensity of, but may not extinguish, the required anti-collision lighting if the pilot determines that operating conditions make it in the interest of safety to do so.
The trap →The "never dim the lights" option sounds like the conservative safe answer but it's wrong. Part 107 explicitly gives the pilot discretion to dim lights when safety requires it.
Field note →One of the few explicit pilot-discretion provisions in Part 107, and it has a hard edge: dimming is allowed in the interest of safety, but turning the lights off entirely never is.
