    Patent number: 10539294
    Abstract: A blind spot warning indication device for an exterior mirror of an automobile includes a light guide member. A plurality of wedge-shaped bosses are arranged side by side along an axis on the light guide member corresponding to a setting direction of the PCB. One side of each of the plurality of wedge-shaped bosses has a light incident end surface for aligning with a corresponding light source. An upper surface of each of the plurality of wedge-shaped bosses includes a light reflecting side having an optical pattern for reflecting and scattering. The reflecting side having the optical pattern is an upwardly convex arc surface. A lower surface of the wedge-shaped boss has a light emitting side. The outermost wedge-shaped boss has the largest curvature of the light-reflecting side compared to the other wedge-shaped bosses arranged side by side, and the outermost wedge-shaped boss has the longest length of the light-emitting side compared to the other wedge-shaped bosses arranged side by side.
