Light Bulb

An electric light with a wire filament.

Notes

A Light Bulb is an electrical component crafted from a wire filament, used as an ingredient in a wide range of advanced items including cameras, street lights, vehicles like the Scorpion and Excavator, and decorative signs. It is a mid-to-late game part, typically produced after a settlement has established electrical power and the necessary crafting infrastructure. Because it appears in so many recipes, keeping a stock of Light Bulbs in a public store can prevent production bottlenecks for the entire town.
