A sign apparatus includes a front display panel and a solid halo panel that are illuminated by a light module. The front display panel is arranged along one side of a frame and the solid halo panel is arranged on the other side of the frame. The light module is disposed within the frame between the front display panel and the solid halo panel. The solid halo panel follows a contour of the front display panel and extends beyond a periphery of the front display panel such that the solid halo panel forms a halo border along the periphery of the front display panel when viewed from a direction toward the front display panel.
