4-5 white pulsating lights heading east, traveling in a straight line then moved into a triangle formation.

Noticed a pulsating white light in the sky, on further inspection noticed it was multiple lights traveling east bound. 3 of the lights began moving from a straight line into a triangle formation. And the the other lights began grouping together as well. After a few minutes the faded into darkness. And the sun began to rise, making it harder to find them. During the event I could see a couple orange lights from airplanes heading south twords the airport. The white ones were not blinking like typical aircraft. Plus I took a 16 second video.
