Electric base light should be relatively easy.
On same tile: Frame (vehicle base) + vehicle controls + battery + light
Can be connected to other things with cables (more lights, batteries, solar panels, generator). But I think you would need to go turn each light on/off separately as they would be separate “vehicles” even when connected with cables.
I wonder if it would be possible to mod in a vehicle light part that would consume fuel over time to produce light.
You can also craft the torch and drop it on ground. It will stay lit and make light until it burns out.
