I was driving North on Route 16 when ahead of me I saw 3 triangle shaped lights just above the tree-line. They were much bigger than surrounding stars or an airplane. The one in the middle and as higher and the appeared to be in formation. I'm not sure if they slipped below trees or disappeared. A few miles further up the road I saw them again this time they were to the west over the Ossipee Mountain range. Again, I lost sight of them. This time I turned around to see if I could see them again. The 3rd sighting was just as I was nearing the intersection in West Ossipee. Each time I was only able to view them for a few seconds. I couldn't find anything serious in the area to explain this occurrence. The first time it looked like tunes of light formed each side of the triangle.
