Red light to port is the port side of a vessel which has crossed your course line from stbd to port.
Green light to stbd is the stbd side of a vesssel which has crossed your course line from port to stbd.
Assuming no other lights, they are both sailing (no steaming light) and you are not yet 22.5 degrees abaft the beam of either one (side light, no stern light.)
