Light anchors determine where the lighting data your materials comes from. Normally, each "Skinned mesh render" or mesh will take it from the physical centre of itself, unless you tell it to take it from somewhere else. You find the slot for it on the Skinned Mesh Render component on each mesh.

You can select all the meshes, and set it to your Hips bone, so all the meshes will see your Hip bone as where it should register light data from. This will cause it to not look as weird in certain places.
