Marvelity Noid Light Test Kit, 11-Piece Fuel Injector Noid Light Test Kit with 8 Noids & IAC Tester, Fits Multiple Car Injection System Types

Multiple Injector Compatibility: The Noid injector light test kit typically includes various types of test lights that are compatible with different brands and models of fuel injectors

Rapid Fault Diagnosis: Simply plug the noid light into the fuel injector wiring harness connector, then observe the light when cranking the engine: steady flashing means the injection signal from ECU/PCM is normal (the fault is likely with the injector itself); solid light or no light indicates an electrical problem. No complex equipment needed—easily rule out electrical system issues and avoid blind repairs

Wide Compatibility for Most Vehicles​: Included 8 noid lights with different terminals fit mainstream fuel injection systems: PFI (Port Fuel Injection), TBI (Throttle Body Injection), SCPI (Sequential Central Port Injection), and Multec2. Works with various vehicle years and models, meeting the needs of professional mechanics and DIY car enthusiasts alike

Extension Cable Simplifies Operation: extension cable reaches hard-to-access harness connectors. You can sit in the driver’s seat to monitor the light—no need to bend over the engine bay. Perfect for tight spaces, boosting both safety and diagnostic speed

Portable and Easy to Use: It usually comes with a convenient carrying case, making it easy for maintenance personnel to carry and use

Expands Diagnostic Scope​: This kit includes an IAC (Idle Air Control) tester, compatible with common flat and square quad connectors for idle control circuits. To test, connect it to the IAC valve wiring harness; the indicator light helps determine if the idle control system works normally. Solve both fuel injection and idle control electrical fault detection in one go
