Help requon sources for EL sheet and battery for ANH Macrobinocs transparency display

Hello all--I have a great set of Macrobinocs and I acquired a photo transparency of the viewer image of the Banthas and sand person as seen in ANH before Luke was attacked from a fellow RPF'er.

I would like to know (via a web link if possible) the best place to acquire the EL sheet and battery that would work best to illuminate the transparency from behind in the Eumig viewer.

Many thanks!!
