We were driving with the car along the Aries river going up to the mountains. It was already dark and there were no lights on the road. The road was following the river upstream. Suddenly there were 5 small lights in a v formation floating above the river. Thew were like 100m high. The car in front stopped to see what the light were and I stopped too. We couldn't see any shape attached to the lights but it was also pretty dark. The light just flew down the stream till they disappeared in a curve.The people in the front car, which I did not know looked at me confused, I looked at them confused. We got in the car and drove away. It was the weirdest thing I saw so far.
