Heya,
I had a thread about this a few months ago (I can't find it now) and we came to the conclusion that the electronics company didn't have the correct ones in both colors any longer. I even scoured the net trying to find a company that had them, but no luck.
For my saber, I cut leds myself out of red and green plastic car fuses and it looks pretty good. Even if you had the real leds, they'd still need to be cut down.
By the way... I e-mailed you back in August about getting a ROTJ bottom-handwheel/pommel end machined but I never got a reply.
