Cover art for Long As I Can See The Light lyrics by Creedence Clearwater Revival

i think literally this song is about a guy who has to go away, maybe because he's lost sense of himself, but he wants to let his girl know he'll be back if she'll have him. so he says he'll be coming back, as long as he can see the light of that candle in the window that means she's still there for him.

this song is about having to go somewhere, to do something that you may or may not be afraid to do, and knowing that when you're done with that, someone will still be there for you. i helped a girl i used to be really close with move away from her home recently, and she's not gonna have things go easy for her anymore, not always gonna be safe in the near future. i told her that if she ever feels totally lost, doesn't know what to do, i'll always be there to fall back on. i'll always have a candle in my window for her. that's what this song has always meant to me, which is so weird, because it was playing on the radio when i said goodbye to her.
