This will put that side into darkness, so that side should fire. Go on the construction. If only one side fires, then take the FLED out for that side. Then debug the side that isn't firing. If your other side now fires then your FLEDs are mismatched and you either need to find some better matched FLEDs or use the schematic at the bottom of this tutorial.
Lets start with some mechanics.
While your soldering iron is heating up, grab a pair of pliers and the paperclip. You need to cut both the inside and the outside loops of the paperclip at the point where the inner loop bends. This will give you aroundd rectangle, the size of which is dictated by the size of your paperclip. By the time you've gotten that puzzled out your soldering iron should be well and truly hot. Attach the fuse clips to a fuse or something that doesn't mind heat.
