Large Size Heavy Duty 3-48V Digital LCD Circuit Tester with 140 Inch Extended Spring Wire,Car Truck Low Voltage & Light Tester with Stainless Probe

Better than a test light and you dont have to get out the multimeter. The point on the end will go right through your hand.

I know modern techs will scoff at test lights as barbaric and or archaeic means of troubleshooting a system, however at the end of the day they are a quick method that can be used to cut down on diagnostic time and headache. This is a nice unit (especially at the price) and a welcome addition to my field box. Does it replace a power probe? Certainly not...but in that same breath, they are entirely different tools as well not even in the same ball park price wise for use as a basic tester. The *only* thing I wish this had was a postive and negative base clamp function (similar to the snap on and higher end units). Sometimes its nice to troubleshoot heavy equipment (AC systems come to mind) by clamping to a positive post and seeing if the ECU delivers ground signal. Not a major fault but one thing that is nice about basic bulb style test lights.

I use this for the diagnosis of many customer vehicle concerns as a dealership service tech. This product is a reliable addition to my toolbox. Very simple and thats exactly what it needs to be. It arrived on time, and the company that shipped it emailed me personally to make sure I recieved the item. They also gave me a few best practices for using their product and reminded me of their 1 year warranty. Great work guys, this is how online transactions should be handled.

Not only a light for testing, but a Volt meter too!

Great company good product.

I love it LED screen lights up makes it visible easy and helped a lot at nights...

Worked like it should good product

Well built. Better built then your regular one

Doesnt work in multidirectional has to have probe on positive and clamp on negative, I have used others that work either way

Great tool, works great, easy to read. Quality Tool - The only thing I would change is the wire color, shoud be BLACK since it is the Black/Negative wire you will clamp to. Saves some confusion and follows color standards better. Actually, any color other than red would be better since it does have a black clamp cover to help.
