Chevrolet probably took fibre-optics to the highest level in 1968 when they introduced a fibre-optic light monitor display on the console of the new Corvette. The system used fibre-optic cables from each light assembly (headlights, turn signals and brake lights) to individual indicators on the centre console just behind the shift quadrant. I believe they were used until probably the 1973 model year when some interior re-design took place.
