In this paper, the second Gaussian and the second mean curvature of the helicoidal surfaces with light-like axis of type IV⁺ is obtained in Minkowski 3-space. In addition, some relations between the mean, Gauss, the second Gaussian and the second mean curvature of the helicoidal surfaces with light-like axis of type IV⁺ are given in Minkowski 3-space.
