Review on 🔧 Lisle 27800 Universal Noid Light: Unbeatable Automotive Diagnostic Tool! by Kenny Loeslein

This little thing tells you exactly what you need, which is whether the jets are opening and closing correctly. I almost changed the computer in the car because I thought that one of the nozzles was not lit. It is impossible without knowing any of them. The suction cup sticks directly to the windshield so you can see the signal from the Noid Light as long as you start the engine. This is very important when trying to work alone. A constant flashing light lets you know if the injectors are receiving a signal or not. A very handy little tool that will save you a lot of time and money. Worth every penny.
