Saw a massive bright green beam of light shoot out of the ground into the sky

I was driving east on Route 222 in central Pennsylvania, a few miles west of Allentown. It was around 7:30 PM yesterday (1 December) and nighttime, but the sky was clear and there was a full moon, so it was a bright night. Suddenly from the south I saw a massive beam of bright green light shoot up from the ground and into the sky. It held there for a moment, maybe ~2 seconds, and then just disappeared. This light was massive, I had a good view of the landscape and it lit everything up for miles around. My first thought was maybe some kind of spotlight or holiday lights, but immediately I knew that was impossible because of the magnitude of the brightness. It lit up everything and was much thicker than a spotlight.
