bar of lights, round orangeish disc "talking" to each other

driving backroads, saw a "bank of lights" moving, and an orangeish disc in the distance, both too low for stars and no blinking aircraft lights. bar moved quickly, until almost over us, it had colored lights and then closer to us turned all white, we sped up to move away because it appeared to moving directly at to fly over us. We turned onto bridge to go to south River Road and were between the two, and noticed the orange disc was flashing/blinking a pattern, and then looked at the bar of lights, and noticed it would remain steady, then blink back the same pattern as if communicating. We witnessed this exchange at least 5 times before turning onto mountain road where we could no longer see.
