I remember 3 pilots crashed a wide body trying to fix a landing gear indicator light bulb in florida.

piston engines will give you a clue: dead foot, dead engine. On twin business jets, the engine performance guages are arranged in pairs , requiring a concerned pilot to look a time or two so to discern which engine is functioning- the one with less output numbers is the one that failed.

Take your time- the life you save will be your own, and the aircraft you will avoid crashing is the very one you are strapped in.
