Maybe there's just the allusion in the whole "Man" idea of it. 21st Century Schizoid Man is more or less about modern man, and how dangerous he could potentially be. There may be some more references to Vietnam, because the song came out around then. The second line seems to support that statement, and the third line really cements it there with the line "He's got nothing he really needs."
The Light seems to possibly represent modern man also, like a light in the "Dark times", let's say.
