i have seen a lot of Classic/ Universe?Henkei Optimus Prime light-up the eye by the GOW add on, now, is time to roll out my latest minor custom... "THE SHADOW COMMANDER" this "Light-up" is quite easy to made it, just need time to do... maybe will try to add some light on the chest also...
Update, added some light at the chest... next will be light up the sword... To add the light on the eye, i cut of the original SC eye and made the transparence plastic eye to replace it. For the chest, i drill the two hole and put the transparence plastic in between the OP and SC chest. it may dig, scratch, drill to the Shadow Commander to added the LED. So, think first before you really want to made it.
