I only have to make readme files and then extract/pack the demo prop set zip.  ^^     Meanwhile, I'll begin the explanation.

     Overall, we'll use three categories of props:

• visible light - this simply may be material areas of your model, or they may be separate meshes
• aura - a "bubbled" mesh surrounding the light
• IDL emitter - usually an offset/scaled copy of either the light mesh or the aura mesh 

     These are three separate props because the object parameter properties (visibility and casting shadows) must be set differently for each category.  I'll make screenshots showing these settings.
     This is the basic double edge blend setup with which to texture an aura.  The edge blend node is sensitive to the angle at which the camera views a given polygon, so it tends to make sharply curved areas very visible, whereas flatter areas tend to fade into transparency.  So, form your aura mesh so that it is a rounded bubble surrounding the light piece.  Be sure to shut off the specular (value=0), otherwise your mesh may look like clear plastic.

     This is a doll textured with a double edge blend aura:

.     This is the basic double edge blend node setup...

.     This material is a strobe light which flashes three times, pauses, and repeats.  For animations, there is no need for keyframes;  the animated material works by running off of the frame number variable node in the material room.  Look at math function node #7; see the "16" value?  That sets the length of the repeat cycle.  So here, it repeats every sixteen frames.

.     This material pulses gently on/off, waxing and waning in sine wave fashion.  Frequency adjustment (a relabeled math function node) sets the length of the repeating cycle.
