Aircraft; Procedure
Upon completing the post flight I noticed both wingtip navigation lights were inoperative on both sides.  I have been incurring this event frequently in the past week and my 6th time so far this year.  The reason I am filling out a safety report is because 1) we conducted a flight and landed with no navigation lights at night time; especially into a busy airport ZZZ.  2) a recurring event that Maintenance just seems to think resetting the NAV lights is the solution instead of looking at why there is such a recurring event.  Perhaps I am incorrect in assuming the latter of the 2 statements but nonetheless this could have had a bad outcome last night.  My previous experience leading me to this thought process is that I had an aircraft last week that was deferred for NAV lights.  I am purely speculating; but I believe it was a CRJ aircraft.  We tried to shut off the NAV lights as directed by Maintenance for 5 minutes.  It didn't work.  So the lights were MELed.  We arrived into ZZZ and then the NAV lights were reset with the lights returning to service.  Maintenance Control indicated it could be the temp sensor could be deteriorating.  But since I have encountered this on so many different aircraft it gives me great concern.  In addition of these two events I had another event involving another CRJ aircraft.  We shut the NAV lights off for several minutes as per the history events prior to this event.  The lights turned back on without further issue.Unknown [cause] at this time; but obviously there is an issue with the temp sensors for the NAV lights or some other issue and must be addressed by Maintenance and the fleet department to avoid a possible FAA infraction and/or aircraft damage because of non working NAV lights.  If you have ever seen an aircraft parked at night time with no lights on; it is nothing more than a black hole so to speak and without vigilance someone could easily run into an aircraft with no lights (I am speaking of on the ground as I feel a more serious hazard than in the air).  Could happen with a vehicle not paying attention especially at busy airports; or another aircraft like in ZZZ1 where aircraft freely taxi with the expectancy of see and avoid other aircraft with very little ground control oversight. [Suggest] Maintenance oversight and fleet oversight to address what seems to be a possible fleet wide problem.
CRJ-200 Captain reports several wing navigation lights are overheating and maintenance continues to just do a reset. Pilot reported landing at night with no navigation lights.
