David Turney, CEO of Digital Recorders (TwinVision) was CEO at Luminator about 10 years ago. He left and then started TwinVision in 1986. TwinVisionn now owns Mobitec and goes by the trade name Digital Recorders. The older style ODK has the TwinVision name, the newer ones have the Digital Recorders name.
TwinVision was the first of the two to come out with the colored LED signs. The first one, known as the Chroma I is the part-color sign. The route number is color and the destination is amber. Later the Chroma IV was introduced, which is the full-color sign. The colors where only available for the front signs at the time. About two years ago Luminator introduced a color line of signs. These included part-color front, full-color front, full-color side and full-color rear. The orange LED Luminator signs are the Horizon series. The newer ones are the GEN4 Series.
TwinVision now makes full-color side and rear signs. Long Beach Transit is retrofitting the New Flyers with the full-color set of TwinVision signs.
Luminator was once the predominate signs in the industry over Vultron. Unfortunatrly, TwinVision has begun to take the major market share.
