Blinking Red Lights Over Texas City

Check out these blinking, red lights hovering over West Texas City on April 7th. They disappear and reappear and are in a strange formation.

From the video description by MrDshook01:
About 20 of us watched the lights move around & slowly fade away. This went on for about 15-30 minutes.

A few comments corroborate the event, like this one from Idd210:
I was there. Wicked thing to see. Deliberate pattern change. Not moving all together. Not a blimp. It made front page news on the Galveston Daily News along with additional video.
