Thank you very much... Now it works great. Here is my code if other has the same problem.
//create twosided lightning for model
osg::ref_ptr<osg::LightModel> lightModel = new osg::LightModel();
lightModel->setTwoSided ( true );
states->setAttributeAndModes ( lightModel.get(),
osg::StateAttribute::ON );
//create material with red back-light
osg::ref_ptr<osg::Material> material = new osg::Material;
material->setColorMode ( osg::Material::OFF );
material->setEmission ( osg::Material::BACK, osg::Vec4(1.0f,
0.0f, 0.0f, 1.0f) );
states->setAttributeAndModes ( material.get(),
osg::StateAttribute::ON );

Below is my try: osg::ref_ptr<osg::Material> material = new osg::Material;material->setColorMode(osg::Material::AMBIENT_AND_DIFFUSE); // switchglColor usage offmaterial->setColorMode(osg::Material::OFF)l // switchings glColor usage off...You'll also need to enable the two sided lighting model via osg::LightModel stata attribute.
