You will need:
4, 3MM LEDs
Wire (I used a CAT5 strand)
A dremmel or a drill
This is what we are going to do.
So drill out your holes for your LEDs.
Next sand down the angle dome on your led so it looks like this (this will diffuse the light better)
Next you want to solder your first LED. Then place it in position. It is important to have the LED head flush with the inside ring of your thumbstick housing. Hot glue her in place and hold it there till you can let go and it wont back out of its hole. Should look like this when you are done.
Now unravel your CAT5(if you are using it) like so.
From here on out it gets tricky to place the LEDs in place. You will need to strip the wire with out cutting it (it is less of a pain then trying to solder 2 wires to one tail). Then bend your tails really close to the head of the LED and solder it, place it. Now hot glue this one in place as well. It will look like this.
The next one.
Now you will need to notch out a piece of your controller so that your wire can pass though without getting bothered by your bumper button or effect its function.
Now the next LED.
Once everything is placed it should look like this.
Now you need to solder your wires to your source whatever that might be. Mine is the rumble motor.
And your done! Congratulations!
Hope you have enjoyed.
