How to and what did I use?

As promised and a bit later than I wanted to here is the How to.
I set my camera on tripod with a remote controlled shutter chord so that I did not pick up any camera shake. I used an ISO of 400 to pick up the christmas lights better for I wasnt using a flash.
When the shutter opened I zoomed the lens out so it would pick up the trail of lights
