Pulsing red lights arrive for fireworks.

A local carnival was having its and three of us were sitting on our front porch listening to the noises and watching the faint flashes.  
We saw two red lights in the direction of the carnival that were slowly pulsing.  They stayed in the same position for the duration of the fireworks and when the fireworks ended they faded away.  
The firework show was a good 14 miles away and all of the light but small flashes were blocked by mountains.
We have corrected the date above.  PD
