To build a light bulb you will need 2 iron 2 copper wire for each light bulb.

Seeing as we are restricted in the number of starters we could use, we are making this blueprint item with just two starters. One will feed the copper directly into a wire drawer,then onto a crafter, the other will fee iron directly into the same crafter. This assembly line has a tiny footprint of just five spaces and works really efficiently.

A screenshot of our setup for the light bulb blueprint is below.
