The Dark Side is strong with the 3.5 inch long Star Wars Vader's Red Lightsaber LED Keychain, but I suppose that is what happens when you use a red focusing crystal or in this case, a fancy LED bulb! They are pretty much the same thing if you really want to split hairs. Mimicking the red lightsaber of Darth Vader and other prolific Sith, the Star Wars Vader's Red Lightsaber LED Keychain shines with the intensity of a Krayt Dragon or a frenzied Rak'ghoul. Let your hatred flow with the Star Wars Vader's Red Lightsaber LED Keychain!
