Thanks, I it works.
I add the sentence as follows,
anotherLight->setStateSetModes(*rootStateSet,osg::StateAttribute::ON);
But I don't know why it should be added?
The LightSource nodes set the position and parameters of a light
source, but they don't swithc on the OpenGL light, with has to be done
with a glEnable, which the OSG wraps up with
setMode(GL_LIGHT0+i,osg::StateAttribute::ON), the above code you have
added does just this.
