The Falcon 9 Footage
The Flacon 9 launch out of Vandenberg AFB on 17 Dec 2017. There is plenty of news footage and other private footage of the same shot out there. Look it up. You got the spectacular light show because of the time of day. It was just after sunset so the rocket boosted out of darkness into the sunshine above and that gave the viewer the wonderfully bright illumination of the plumes and stage separations.
