The lyrics reminded me to an historical fact. In ancient times (about the Egyptians and Mesopotamians), there was a tradition in which when a family member was going to hunt or to a long travel, they lit a candle until his return "to light them the way back".
According to this, I think that the song is referring to a close someone that has been emotionally hurt or that is lost, and you are lighting them their way back to the people that care about them, even after all the things he or her had done.
