How do I navigate through [Spoilers] without a [Spoiler]?

So pretty much when I was exploring the map I got myself into a sticky situation where I had to leave, but I didn't realize I dropped my light. Before I knew it, I already hibernated and so my light is gone. Should I keep exploring or should I try to find another light as quickly as possible?

your map will always show you geometry even if you don’t have a light source
