Need Lighting help(Maximillian Vlack Hole)

[Zen-Builder]

Hi All.

I got a "Maximillian' kit from the Black Hole and would like to add lights into the Head.

I know lightsheet would be the best(AFAIK), but I don't have access to it here. Any suggestions how I could give the clear part an even glow using LED's or similar.

Electronics, batteries and switches can be contained in the body.

Thanks in advance.
