Black Triangle Sighting in West Haven, Connecticut on October 30th 2015 – Strange light high in the sky over the water several times a week

I live at one of the highest points in West Haven so I have a clear view of the coast for many miles. For several months I have noticed a strange light high in the sky (at least once or twice a week and sometimes more often) that seems to be over the water. It���s a very bright flickering light that looks diamond shaped sometimes and triangular in shape other times. I���m not sure what town it���s actually over but I assume it might be New Haven but could be as far away as Branford or even Guilford. I usually see it between 2am and 4am and it���s usually out there for at least 1 hour before disappearing. It���s always high in the sky and does not move for that particular night, however every night that I see it, it���s not always in the same location that it was the prior night when seen. For the past 2 nights there were 2 of these lights out there not far from each other. I���m really not sure what these lights are but there is something out there and just wanted to report it.
