Illuminated looped light pipe

The invention relates to a light pipe illuminator. The invention is of particular advantage for use in illumination of dials and knobs. A light pipe illuminator comprises a looped light pipe defining an endless light path, the looped light path including a substantially planar front surface and a faceted back surface comprising a series of angled facets arranged about the loop and arranged to reflect light towards and through the planar front surface and a light input port through which light is fed into the light pipe substantially along the light path, the walls of the light pipe arranged such that light entering the light pipe travels about the loop such that the loop is illuminated through the front surface
