Triangle formation of lights

I was laying in bed at night and looked out the window and normally am able to see
Planes at night due to being in the flight path however I did not see any on flight tracker in the vicinity. I saw three very bright white and orange lights that formed a perfect triangle. The lights were pulsating in and out forming a larger triangle then smaller triangle changing size all while maintaining its shape. I also saw another small bright white orb up to the left upper side of the camera view. All of a sudden all of the lights compressed into one and
Shot away in a very fast not normal flight pattern that I have ever seen.
