ABSTRACT:
A flashing signal light that includes a rotatably mounted signal generator formed of a light transmitting material and a non-rotatable source of light adapted to direct light into the generator along its axis of rotation. A pyramid shaped prism is associated with the generator having its apex positioned along the axis of rotation. The prism surfaces intercept the light directed into the generator, split the light into one or more beams and direct the beams towards the exit face of the generator in a plane that is substantially perpendicular to the axis of rotation.
