I used a typo LED light which comes in two in a box for $19 Australian
I used Darth Vader black filament of course and about 3 hours in I changed the roll for a little bit of red then I went back to the black. That touch is up to you but I think it brings the devil out of the lamp with that colour.
There is also a little cylinder which I glue to the end of the typo light which has a battery compartment near the bulb.
the light turns on when you pull the cord so i thought I would feed the light from underneath and the cylinder works as a stopper if you want it that way. Otherwise have nothing, the hole is a tight fit so I had to warm up the lamp hole with boiling water then I fitted the typo light and its tight in there now.
I hope you enjoy it.
when you make it make sure to add photos. thank you!!
