Coming from being a professional boat skipper (recently retired) I can add to this idea because the vessels I owned were all fitted with AIS transponders, AIS stands for Automatic Identification System.There are other thing beyond lights and frankly lights are the least of it as it's almost certain that sooner or later we will all need transponders -- altitude, heading and speed and ID reporting transponders.
Currently AIS on ships is only available to holders of a DSC VHF radio license and the license number is used to activate the AIS transponder.
An AIS system would broadcast all the flight data required to be able to track and identify an aircraft fitted with AIS.
