How to give custom sword lightning?

[Xioth]

How do I give a downloaded sword lightning? Like the sith sword. I've been tinkering around with it, trying to find a way to give it lightning, but to no avail.

 

Also, how would I go about changing the color of said lightning.

So, I think I figured out PART of it, I got the color to change and got the lightning to work, but the sword is too vibrant with that color now, and there are weird graphical glitches when there are people with two sith swords.

 

On top of that, the sword isn't lit up all the time like Ragnos' sword, and it loops a bit when a sound comes up.
