Only because my donor had them, I have installed idiot lights for Alternator, Low brake fluid, Low oil level, Low fuel level, hand brake on.

IIRC, the alt light was required for the alt to function at all. It needed to be an incandescent bulb, not LED. I could have used a resistor in place of the bulb I guess.
I only found out later that the low fuel sensor needed a higher power bulb to function properly. The sensor is a NTC resistor and wired in series with the light. the current runs thru the sensor and light bulb. When the fuel is high, the fuel keeps the sensor cool enough to not illuminate the bulb. When the fuel level is below the sensor, the sensor heats up and the resistance goes down causing even more current to flow. Eventually there is enough current for the light to light-up. I never chose to fix that.
I have gauges for speedo, tach, oil pressure, coolant temp, fuel level and voltage.
If you are using the OEM ECU and normally have no "fault codes", I think a check-engine-light might be a good idea.
