The 68-72 had fiber optics. There is a little panel in the console that indicates what lights are on, and when they are blinking.

EVIL GRIM:

Actually, the fiber optics were a standard feature on the '68 thru '71 models only. Deleted in '72 for offsetting the alarm option as a standard feature in this year.

There is a separate panel that sits in the center console area between the radio and shifter console plate, also integrated into the lower end of the shift console plate are fiber optic lenses as well.

These lenses transmit light that eminates from different sources like tail lamps, brake lamps, headlamps, signal lamps, license plate lamp. Each lense has a different color to distinguish what is functioning. Such as red, yellow, blue.

You can tell if any of these items are not functioning by seeing that they do not light up, or blink.

Kinda of makes the whole C3 cockpit resemble a small airplane dash like area, when lit up at night!!

I think the fiber optics are a great bit of engineering design. You immediately know whether or not a bulb has burned out. With other types of systems, you don't know whether the headlight is burned out or whether the light bulb in the dash has burned out. These other systems have to have some other function to test the dash bulbs which makes them overly complex...
