Cluster of pulsing blinking lights making formations

Wife and I pulled up to the winery in Taylorsville Georgia. Before I could put the vehicle in park both my wife and I looked at each other and said, "What is that!" I immediately exited the vehicle. On the horizon, there was a cluster of moving and blinking lights. Some of the lights were blinking red, some greenish blue. Some were small. Some were larger. As I pulled my phone out to record, the cluster began shifting and formed a perfect "check mark" symbol. As I filmed, the farthest light to my left slowly faded out and reappeared, becoming the farthest light to my right. When the lights formed a straight line, I decided to go into the winery to tell others to come and see. Three males and a female came to see. Everyone was in shock. The older gentleman seemed more frightened to me than shocked. We all stood and watched for 5 minutes or so. After everyone went back inside, I filmed the lights once more. At this time, there were only four lights visible. They had split into two groups of two. Each light in each group maintained the same distance from one another. Both groups moved away from one another and a 45 degree slant to the horizon. There was no sound and the lights seemed well within hearing distance for an object like a helicopter. I'd also like to add the the lights were between Taylorsville and Dallas. Other than a few houses, there's nothing between the two but a large forested area.
