4 different spherical lights of different colour. Rapidly moving.

At approximately 2:45 am, I whitnessed 4 spherical lights around 40-50 feet in the air.  The sky was clear, as it was a cold winter morning.  2 of the lights were white in colour, and 2 were more yellowish..  There was no noise to suggest farm machinery, etc., or an aircraft.
What drew my attention to the lights initially was the fact they appeared to be moving in a rapid figure 8 type motion.  At first I thought they were flashlights belonging to poaches, however as I stopped my car to watch them I realised they were way too high to be this.  I stopped in my car for around a minute to observe the lights when they appeared to stop as though they were looking back at me.  I definitely could not see a single craft of any sort, but these lights moved with such fluidity and speed.
I've no shame in admitting I became very uneasy; something about the situation just did not feel right.
I travel that road every day around the same time. I admit I have never really been a believer in phenomenon etc but this incident really has made me think.  It has affected me to the point I feel uneasy to travel that road now.
