  • a base mountable internally of the buckle housing;

    a light source mounted on the base, capable of emitting light rays; and

    a waveguide lens mounted on the base, the lens having a light-transmissive input surface aligned to receive rays emitted from the light source, a light-transmissive output surface configured to be placed proximate the opening slot, and oriented substantially orthogonally to the input surface, the waveguide lens comprising an integral injection molded body of transparent optical-grade plastic, the body coated with optically opaque material on its exterior surface exclusive of the input surface and the output surface, to cause redirection of light rays received at the input surface by internal reflection to the output surface.
