After a long time searching, I finally found two Walthers hot metal bottle kits at a hobby shop near my son's house. I would like to put an orange light into the cars to stimulate the molten steel. I was thinking of installing a battery and an on/off switch to operate the lights. Please let me know if any of you have any ideas or have successfully tried this on your own cars. Electronics is not my strong suit.

Also, I don't know the best way to simulate the accumulated crude that in found near the opening where the steel would be poured.
