Two flying objects with bright lights on the front and red and green lights on the wings

We (a young married couple) saw two motionless bright lights in the sky on our way home from a friend’s house. Even though the lights didn’t move like a plane, they were not stars. They were much too bright to be stars.
After a while one turned to the east and started flying in that direction. After it had turned, we could see that it had 1 red and 2 green lights on either side. In the meantime the other light had begun to ascend and descend in elevation in an up and down motion. Eventually the second light also suddenly veered off to the east and revealed the same light pattern as the first.
