Lyric discussion by DaynaRix 

Alright, I know other people have said this, but it seems like some people still don't get it (not being snarky- just honest).

It's understandable that a lot of people don't get that "putting on a red light" refers to going out and being a prostitute.

The Roxanne the song refers to is a prostitute. The speaker has decided he is in love with this prostitute, and he wants her to quit. He is telling her that he could support her, so she doesn't have to put on the makeup and the dress she usually wears to sell herself. When he says, "You don't have to put on the red light," he means that she doesn't have to go out and sell herself anymore, he is going to take good care of her and respect her.

Of course, this is just my humble interpretation, but I hope I have helped some of you guys understand it.
