Christmas lights are a tradition that, while exposed to in my youth, I did not fully experience until an adult. I remember thinking during my freshman year in college that a "hay ride" through neighborhoods festooned with Christmas lights was dorky and gay at best, but actually having gone on said "ride" I must say it was actually pretty entertaining. I would have balked at caroling and wassailing, but hot apple cider and fanatical light shows are surprisingly satisfying.
That said, I never saw anything that comes within even spitting distance of this display, found on youtube:

It's a Christmas light show set to the disco tune "A Fifth of Beethoven."
