I truly hate to be a buzz kill here, but seriously... these cubes can't possibly put out enough light to do anything but help the pilot see the aircraft. However, as those of us with 107 certification already know, I'll post the obvious:
SECTION 107 CERTIFICATION RESTRICTIONS:
“(a) No person may operate a small unmanned aircraft system during night.
(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. The remote pilot in command may reduce the intensity of 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.
So, here's my point: if the FAA quite rightly thinks it's an unacceptable risk (without a waiver), for commercial flying, then how can a hobbyist pilot think night flying is a good idea, even though you CAN do so legally? Just not a great idea for most.
