Formation of four light that appeared as two at first and kept in formation but appeared and disappeared numerous times. Clear skies

While I was driving to work I start to lights stationary above the San Bernardino Mountains. I was driving east on the 10. All of a sudden it became 3 and then four and then three and then two and it continues to do this in formation for at least 10 minutes. w I was driving to work. I took pictures and video but I couldn't see anything. I have an Android. I called my daughter while it was happening and told her what I was seeing. I will mention here that there were a few other shapes maybe three or four that were up in threw sky as well. Maybe cigar shaped.
Like a thick line of white and all the same size and they were flat and they didn't move either but at the time I wasn't sure if it was just something natural but I definitely noticed that they all seem to be together.
