3 lights in formation

While driving north on 35 I noticed 3 green lights in a triangle formation. They came closer together then further apart but stayed in triangle formation. Be cause I was driving, and had to watch the road I looked away then back to the same spot but lights were gone. Suddenly they appeared in a completly different place in the sky. Further than any human craft could move and one of the lights turned from green to red. Lights moved apart then together again and the red one turned back to green. I exited the highway to hopefully get a better look but trees blocked my view of the sky. I pulled up a flight tracker app and there were no planes or helicopters anywhere close to the area.
