Light and Dark Grabbers

[A_Li_N]

I didn't like the fact that you couldn't grab the light/dark sources, so I made these little guys. They make their own lightsource that can be changed by propsing the grabber.

I did notice however, that my Darksources don't shine their darkness...any ideas why this is so?
I tried adding the static tile, the darksource item and my darkgrabber, none of them showed their darkness. I tried lightlevels both 0 and 12. Any thoughts as to why this doesn't show for me?
Thanks and enjoy!
