Along the lines of the headlight on the steering wheel to grab attention. Did any mfg ever do something along the lines of combo instruments and idiot lights?

I vaguely remember reading an article in the 50s or 60s when fiber optics and light pipes were coming on strong and all the how-to magazines were dreaming up or in some cases documenting uses. One of the illustrations was a combo gauge. The car had instruments but when a problem occurred, to get the drivers attention the whole face of the gauge turned into an idiot light by virtue of a light pipe channeling the red light into the plastic face of the gauge.

Can't remember if that was an actual or fanciful way to use the light pipe. I know the color changing speedo needle or indicator was used by many including Packard but how about instruments.
