Turn Hasbro Dooku saber into LED type

I'm planning on converting my Hasbro Dooku saber in LED in hilt. Any ideas on how to build one together? It doesn't have to have fancy features, but just more simple, I guess. But yet keep the sound board itself.

do-clo has made a couple of those. maybe give him a holler.

I saw those on Ebay, but I can't remember what they went for.

I think the Dooku Hasbro is too clunky, but then I have small hands, so most hasbros bar the quigon are too clunky for me.

Any of Do-Clo's work is worth every penny though Matakin! :D

Thanks though. Yes, I've heard of Do-Clo. I've seen his Dooku saber on Ebay.

All Hasbro sabers are too fat for hand. Yet, I consider doing it more for me (Anakin) vs. any Dooku at cons. For dueling purpose.
