An illumination apparatus comprises an elongated waveguide having proximal and distal ends and a central longitudinal axis. The waveguide includes an elongated forward side for outputting light and an elongated rearward side having an elongated reflective surface for reflecting light towards the forward side. A light source such as a solid state light emitter may be situated on the proximal end of the waveguide introduces light into the waveguide in the form of a beam which propagates from the proximal end to the distal end. Light traveling within the waveguide is reflected from the reflective surface along the elongated rearward side towards the forward side for viewing.
