A noid light is a diagnostic tool used to check the presence of electrical signals at a fuel injector connector in an internal combustion engine. When connected, it flashes in sync with the injector pulse, indicating that the engine's computer is sending the correct signals to the fuel injectors. If the noid light does not flash, it suggests a problem with the injector circuit, such as a faulty connection, wiring issue, or a malfunctioning engine control unit (ECU).
