I saw a bright light in the sky that looked like a giant flashlight that was moving in a backwards direction-

I was moving SOutheast on Princess Anne Street in Fredericksburg near the train station, and high in the sky I saw a very bright light that was moving from right to left, but the light was pointing to the right. The light was very very bright, pointing to the right, but it also had a large cone of light associated with it- Like a giant comet or something in the sky- It really reminded me of pictures of a comet, where there is a huge tail of debris, but there was a bright light pointing backwards as it flew- It was not like any airplane I had ever seen.
