Several round orbs of light flying silent 1 after another right above the tree line

I heard fireworks going off in the distance while on the phone in my driveway about to leave when 2 round bright orbs started to come over the trees so I grabbed my other phone to record as I thought there where no more 2 appeared from the same path following each other then another followed as another followed then stopped. I then left to follow them as I pulled down the street and took a left on jog hill rd 2 more following each other in the same path as the others so I quickly recorded them as they pasted over the trees I turned downed Daniel's farm rd I witnessed a cop car stopped in front of the Trumbull high school farm witnessing the same balls of light I saw. I tried to follow them but they began to quickly sped up and took off in the distance headed south it looked like toward Bridgeport, CT. I was in shock with my girlfriend on the phone the whole time giving her a play by play. I took videos and still shots. Definitely where no Chinese candle things in a bag as ppl tried to say it was from my videos because these balls of light where intelligent and moving at different speeds. I know I couldn't have been the only person to see this. Some ppl that night may have brushed it off as fireworks but these where no fireworks or plane or helicopter. Not to long after I witnessed 2 helicopters flying low and fast. Maybe government idk.
