Observed one floating and lighted sphere, and then either one lighted rotating triangular craft or three separate crafts in formation.

My partner and I were sitting on the balcony of our condo when we noticed a strange lighted object in the sky, above the tree line. It was moving up, down, and horizontally. The light changed brightness and at times would disappear completely and reappear in a different location. After the last time it disappeared, it looked like there was either a triangular craft rotating, or three separate crafts rotating in a triangle formation.
