Here's a little mod I did a while ago.
Look closely at the pic and you will see that in between each vertebra on the "Bony Beast" there is a Green light.
This is simply 12v round ELwire threaded through the existing holes in each vertebra then cut to length. This is tagged to the 12v flasher (now a Green 12v Ablaze LED)
Naturally the effect lights up when the flasher comes on.
It's very easy to do and the ELwire from China was cheap as chips.
Keen observers might note the Beast's eye sockets (orbits) have a red film in them - courtesy of GAP (Graeme) another excellent mod for this game.
Sorry the photo does not do justice to these mods.
