What you need-
One tri-wing screwdriver
One 3mm LED of you color choice
One soldering iron with solder
About 3 inchs or wire.
One wiimote (duh)
Step 1: Take your wiimote apart
WATCH OUT: watch it the front of the wiimote has clips that hold it in place nad if you pray the wrong way they will break off, causing trouble, what i do is pray the back up alittle bit then stick a butter knife in side and pull up.
