Re: Foolproof is not enough
No, they are called idiot lights because they are there as a cost reduction by bean-counters over functional gauges. Idiot lights only tell you when something HAS failed, as opposed to a gauge with an educated driver who can see that something isn't right and stops and has it fixed BEFORE it fails. Good examples are the ammeter gauge and oil pressure gauge.
I'll take the gauge any day over a stupid light.
