Leaving a light on has always been a sign of waiting for someone to show up at your house, which is why we light candles at christmas and put them in the windows, we're waiting for the christ child. In this song he's basically addressing himself and the "lonely boys" like him who struggle through life and survive by the hope in their dreams of a better life. He's telling himself to make the music for them b/c it frees them from the bleakness of their lives...IMHO
