The light kit is probably the same one I installed in my Centurion I just finished. It's appropriately called "TinyCylon" kit, and can be found on ebay for around 12 dollars. I would assume the sound is similar to what I used as well, a simple MP3 recording loop, which isn't too hard to come up with. I'll try to post a few shots and video of my build soon. I think you did a fantastic job on yours as well, BTW. Congrats!
It really does built up into a great Centurion, even though the wiring space can be a pain in the asteroids at times! My leg joint at the hips was a bear at times as well, but well worth the headache.
Again, great build job!
Sincerely,
Scorp.
P.S. - Just watched the video. That looks like the TenaControls Centurion light set. Thought about using that in mine, but I didn't want to do the lights in the guns. A very impressive build indeed!
