How to get moving light effect on pictures taken from nikon d3000?

Camera on a tripod iso100 f11-f16 about 15 seconds on bulb setting. Used a remote trigger to avoid blurring. Or you can set one of the fixed time settings and use self timer if you don't have a trigger release.

Leave the shutter open for a few seconds. Use a tripod and shutter release cable if you have one.
