I managed to do it no sweat.
What I did was draw the lightening bolt in white using the pencil tool on a new layer then duplicate the layer twice. I used eye candy gradient glow in red on one mask and blue on the other. Then using the polygonal lasso tool I cut out the opposing halves. If you bring the original bolt forwrd you have the white line.
I liked the effect better when I took the original bolt and used gradient glow white over top and reduced the opacity.
