Step 11Eight and Eight is Sixteen
Take two X's of LEDs and use handy-dandy clip leads to hook up all the positive sides and all the negative sides. Your trusty 8.4 volt battery will still power them all, because we're putting two LED X's in parallel, which means they run on the same voltage, but just take twice as much current. (So your battery will run down faster, but who cares? It wasn't that great to begin with...)
Now that you're steeped in LED science, you can follow the schematic on your own.
