From the YouTube description of the video:
This video was taken the NBC 7 crew in San Ysidro. Several viewers also told them about the lights. Some said they appeared to be red, blue, and green and kept flashing and changing colors. Some who saw them say the lights didn’t seem to move, like those on a plane or a drone. NBC 7 put in calls to the military here to see if they could identify what these were. So far, no response.
