Stupider question: could the light ever be useful?

My 89 SPG has an upshift indicator light. Yes of course the light is useless under ordinary conditions (i.e. if everything is working properly), but I wonder if it can give you an early warning about an engine problem. For instance, on two occasions my shift-up light has started blinking weirdly: once I found a major vacuum leak and another time I had an idle-control valve problem. I don't know the system very well, but that light is controlled by engine speed and by throttle position, and if something is wrong with those sensors, I suspect the light could give you some clues.
