I have a roombox that I would like to use as my Christmas card this year. It seemed a little dark so I bought two off the shelf Christmas village street lights, cut them up and installed them in the ceiling.
Step 1: Prepare the Street Lights
Cut the wires leaving an inch or two sticking out of the fixture.
Step 2: Installing the Street Lights
On the fixture twist together the two yellow wires and the two red wires. Using a soldering iron, solder the red to one of the main wires and the yellow to the other. Make sure the red and yellow don't touch by having one color a bit shorter than the other.
Carefully pull the wires up through the holes and wrap with electrical tape.
I finished off the top of the lights with a small piece of rolled fimo.
