You need to light up your life with torches and lamps.

You can burn through some resin if you try,

As soon as electricity came to Valheim (i.e., wisp torches, the single best feature from the Mistlands upgrade) I replaced the majority of the lighting in all my bases with wisp torches. I still keep a few sconces, braziers, and pumpkins around for ambiance, but I no longer have to pile up mountains of resin and greydwarf eyes to keep my places lit!
