It seems no matter what type of game it is, someone's going to try and put lightsabers into it. Same is true for Skyrim. There's now a mod that'll give you that Star Wars feeling by providing you with a multitude of colors in both one handed and two handed variations.
You'll need Daedric smithing to be able to build one, or you can cheat via the console to do so. In any case, the mod gives you sights and sound of carrying around one or two lightsabers. So, if you're a Star Wars fan like many of us are, check out this mod to bring some Jedi justice to the folks in Skyrim.
Sorry console folks, this is only for the PC version.
