Lightning Particle Emitters

I'm looking for a good way on how to make lightning as a particle emitter. I'm not for sure how I can but I'm looking for a way on how to make it.

This is my code so far I'm not doing so well so far if anyone can give me some advice on what I can do to make it look more like lightning I would appreciate the gesture.

datablock ParticleData(lightning_pd)
{
textureName = "~/data/shapes/particles/lightning.png";
lifetimeMS = 500;
lifetimeVarienceMS = 60;
//gravityCoefficient = 1.0;
windCoefficient = 0.0;
sizes[0] = 0.1;
sizes[1] = 2.1;
sizes[2] = 1.0;
times[0] = 0.0;
times[1] = 0.5;
times[2] = 0.75;
};

datablock ParticleEmitterData(lightning_ped)
{
particles = "lightning_pd";
thetaMin = 0;
thetaMax = 0;
phiReferenceVel = 0;
phiVariance = 30;
ejectionVelocity = 1;

};

datablock ParticleEmitterNodeData(example_pend)
{
timeMultiple = 1.0;
};
