Step 4: Solder the LED
If the LED lead fits, secure the lead inside the last bead of each pin, making sure the LED lead and pin overlap.
Solder the LED lead to the beaded pin with the wire, making sure that you do NOT solder the wire accidentally. You will be soldering the wire to the opposite pin.
Wrap the stripped end of the wire around the LED lead and pin (without wire). Solder, creating a nice solder joint.
