1. An optical waveguide based side illuminating assembly, comprising:
an elongated, side-emitting light waveguide;
an optical protective coating surrounding the waveguide;
an elongated base to which the waveguide is attached lengthwise along the elongated base, via the optical protective coating;
a reflector that extends lengthwise along the base and is disposed between the optical protective coating and the elongated base; and
an elongated reinforcing structure that comprises a flexible rod that is embedded in the elongated base and extends lengthwise along the elongated base, wherein the flexible rod is an optical fiber.
