Triangular shape craft with 3 quite large white lights at each point

Around 3:30 AM of the morning if the 27th of April I seen a triangular shape craft fly over my house why I was outside smoking. It came from the north heading ruffly south south east. It had quite large white lights at each point of the craft and by the one on the back left was a red and white flashing light just like the FAA requires on aircraft. It looked like a big flat triangle. It sounded like a jet but I could not see any engines or exhaust. It was moving about the same speed as a small plane would have. I watched it fly away and the same steady speed until it was out of sight.
