So I know that there a lot of LED versions out for Ravage. I also know a lot of us aren't stars with soldering. So I made one with a Lego Lightbrick. They used to come in the EXO force line and are basicly a LEGO brick that is transparent, holds a battery, red LED, a push switch and a whole to put the tube in. The tube lights up a bit and the end lights up a lot It looks like this: It cut the lightbrick a lot smaller. You can take of a lot! It fits in the chest now I didn't need to joint the neck, because the tube joints the head with the body. Here I pulled in out a bit: Normally the head is against the chest and you dont see the tube. If I turn this screw it pushes the button and the light goes on I hope this helps some of you! Be sure to buy LEGO parts on bricklink.com! It is sort of a LEGO E-bay where you can buy separate parts, also joints you could use for combiners..
