Falling Sparks from Hovering light

Sighting #2 in North Washington/West Sunbury - PA While driving home (North-on route 38) from dinner (8:00pm) with the family. Weather was cold, 20's-30's, light wind, broken clouds. I happened to look out to the left (West) and I thought I saw a light DROP DOWN (fast) from the sky and stop dead in the air... Immediatly I rolled my window down to eliminate the possibility of a dashboard light glaring from inside and causing this anomaly. It was still there, and now was turning a light yellow-orange color. Seemed to be approx. 2-miles away -Just then I slightly ran off the road while watching this happen (wife let out a gasp -a girl thing). The next event I observed (almost slammed the brakes on to see this) was a shower of molten materials[?] and sparks 'dumped' to the ground (LAKE? see map) Then it seemed to turn a brighter color yellow-white and Blinked off or faded-out very quickly. My wife was to hysterical from me running off the road to notice what I was gawking at... I did notice (a few days later) that there is a large  secluded pond in that same area (could this be a covert dumping of spent fuel?) Evidence may still be at the bottom of pond, a great hiding place...
I was reluctant to report it because I thought I would be ridiculed for what seemed to be impossible, but, in a recent sighting report I happened across, another witness saw something VERY similar. I have since learned to trust my observations and keep an open mind to any possibility...
NOTE: This object SEEMED to perform this feat with a military type precision! Quick and precise.
