5 orange lights steadily blinking over the lit up baseball field and then after 5 minutes faded until no longer visible ((anonymous))

My husband and I witnessed 5 lights with the color of a true orange hovering over one of the lit up baseball fields in the area on our way home from the grocery store.  They were synchronized and steadily blinking close to the tree line.  
After a few minutes they continued blinking but faded until they were no longer visible.   The formation didn’t necessarily make out a shape but you could tell it was massive.  The outline was a foreign object incomparable to anything well known or we could make sense of.
