Had my first experience soldering wires on LED 0603's.  Magnet wire is 36g and is the size of a hair.  It is coated for insulation and to make a connection you have to burn the insulation off.  The LED has to be fluxed and solder put on both the positive and negative side.  Care must be taken as the LED's can be destroyed by overheating.  Also care must be taken as LED's must have a resistor on the Cathode side (negative) or it destroys LED.

The first one took over an hour and I destroyed 2 before I got one to work.  2nd one went much better, took less than 5 minutes.

The last picture is both together using different resistors to change brightness.  The little teesting rig is a 9 volt with leads soldered on and different value resistors on the negative lead so you can check brightness you want.
