In this paper, we will investigate 2-symmetry type curvature conditions of a lightlike hypersurface of a semi-Riemannian space form. Then we find some results related with locally symmetric and 2-symmetric lightlike hypersurfaces. Finally the relation between semisymmetric and 2-symmetric lightlike hypersurfaces will be given.
