Yes, but it's vague and probably on purpose. RC fixed wing recreational aircraft fall into the same rules and night flying is and has been a common hobby among the fixed wing crowd for years. Too many feel this is a drone only rule...it isn't. The FAA now considers all fixed wing RC aircraft as drones. I think the wording drone is pointed toward drone operators for obvious reasons.
6. Do not fly at night unless your drone has lighting that allows you to know its location and orientation at all times.
As far as orientation, one can argue about the term. One method would be to use colored strobes similar to full sized aircraft but a different thought might be if a single strobe flash or lighting system is enough to maintain VLOS and aid in navigation. It is not specified. So if I can see the aircraft, I can see its movement therefore I can determine its orientation to fly safely and aid in giving way to manned aircraft.
