I have fitted one of Rudy Pando's crystal-chamber reveals and I will include the battery compartment, LEDs and micro-switch which I have not yet installed. What I have done is put a couple of LEDs inside the clamp area and this is shown in the pictures with a 9-volt attached to show the effect of the orange and pink lights. This can be taken out if you don't like it and Rudy's LEDs fitted in the correct place. It's an easy swap.The item "Star Wars Ben Obi-Wan Kenobi ANH Lightsaber with Crystal Chamber.
