Almost every night for the last 3 years these lights that change color green or orange show up wherever I am they just hover and follow

Every night past 3 years these things travel on the side of me at night they change colors green and orange the look blimp shaped sometimes the have flashing lights they stay hovering all night until sun comes up my cousin has witnessed them come right up on top of my vehicle at first I thought they were drones but I can’t pick there signal up they change when I photograph them I have so many pictures and videos it’s ridiculous it’s also very annoying already I don’t necessarily think there aliens but it’s some type of unidentified object
