🔧 Lisle 27800 Universal Noid Light: Unbeatable Automotive Diagnostic Tool! Review

This is the third test signal I have for a 6 or 12 volt device. Radio, headlights, injectors, coils, EGR, solenoids, yes 6 volts just not that bright

This is 100% the best addition to my tool box, it helps a lot in diagnosing electrical problems in my cars and helps me a lot in learning auto repair skills.

Bought this because I keep losing single Noid bulbs and this one is big enough that I don't notice it's missing, seems to work well and big pluses you can check it out Stick your windshield glass when you test, another big plus if you can replace a lightbulb

40+ reviews list all the great benefits this Noid flashlight brings. The only downside that some people mention is the storage of spare tips. The yellow cap/lens unscrews and there is built in storage next to the bulb, screw the lens back in and voila. Read the reviews and Q&A section and then order this wonderful tool.

Great for checking injector performance. Small and easy to store in your tool box. The extension cord makes it easy to fit a warning light to your windshield so you can see at a glance how the bulb is working when you power the injectors. Makes it easy to find out which injector may be malfunctioning/disabled.

An essential tool! Used this to check injector performance on a Buick Regal 03. No power was detected on cylinder #3, resulting in code PO303. A wire was found burned and shorted out by a hot pipe. Save me a lot of money at the dealer. The standard 12 volt testers don't work when I test the power to the injectors on my machine! Many more uses for this inexpensive tool! Six stars or more if I could!

Smart and well thought out tool. Made in the USA. Fits a variety of fuel injectors; The long light cord makes checking the injectors a one-man job. The cord wraps around the lamp for easy storage, and the regular bulb is easy to swap out. This is a well made and durable tool that should be in your fold out closet; with other special tools to make your work easier.

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…
