UFO with two 3 lights in triangular shape

A friend and I were driving east/Northeast on Andrew Johnson Highway when we saw two lightsts in the sky at a red light near businesses in the eastern part of town- coming into Greeneville from the Afton area, that turned into three lights. The lights were not flashing. They did seem to move. There was no noise. There were other cars around at the time. It was approximately 9 PM on January 6, 2023. We were able to see the craft for about another minute. It seem to be moving east in the sky slowly. After the object had moved on slowly, we observed what was maybe a helicopter with red and green lights, heading toward the direction of the triangular craft but not following the craft closely.
