1. A method of making an illumination device capable of simulating neon lighting, comprising the steps of:

  • forming an essentially solid rod with a predetermined length and a pair of lateral surfaces from material having optical waveguide and light scattering properties such that light entering a first of said lateral surfaces is caused to form an essentially elliptically shaped light intensity pattern that has a major axis in a direction substantially parallel to said predetermined length;

    placing a housing having a pair of spaced walls defining a volume in connected relationship with said first lateral surface;

    bending said rod and said housing into a desired shape;

    positioning a plurality of spaced point light sources connected to a flexible electrical connecting member within said volume between said side walls; and

    essentially filling said volume with a potting material transmitting light.
