Why does it seem that most of the programmed light shows are using the same song. The first house that hit the web years ago, then the Miller Brewing house (seen in the ads on TV), replays on football highlights this weekend, and this house. All the same song. Something about imitation?
Maybe next year, but mostly you expose for the lights, which means like fireworks, you can shut down quite a bit more than you think, use a fast shutter speed and still get nice lights as dots.
For fireworks you probably want to shut down more, use slower shutter speeds and get streaks of light, but you can also capture sharp, frozen light displays as well.
Nice pictures everyone. Maybe next year for the contest of the month in December (hint, hint

) the subject could be Holiday Lights. Yes, the 4th is a holiday too, so anything from the whole year would fit, but also Christmas lights.
Good Strobist article is for balanced light with background and lights, which is more interesting.
