A must have gem!
There are many ways to test automotive fuses, connectors, and wires, but a tool like this is the easiest that I know. I have been helping someone out with their car and had to check all of the above, plus relays. This little gem made the job go much faster. What a bargain! It works flawlessly!

Iโm very pleased. A great addition to any home garage tool bench.
For the price, itโs a well welcomed addition to My Tools. To make your tools and instruments more resilient and resistant, I, always, before ever using, I use a high quality wax, especially โDiamond Coatโ nano wax , coat the entire surface about four times over, which prevents any oils and grease from staining. A clean pass of a shop towel and as good as new.Why did you pick this product vs others?:Price and how complete for My Works.Works well:Like a charm.Functionality:For testing quickly without need to whip out the multimeter.Build quality:I am happy with its design.Quality:Very good, with proper care, shall last.Ease of use:Simple and fast.Cable length:About 2 M stretched out fully w/o damaging.

Test light easy to use bright LED display.
Quality Test light with voltage reading. Very easy to use clip onto a ground wire, and then test fuses or to see if wires are live.

I do not know how any mechanic can show their self such a simple fact about supply voltage.
This tool is so much more than a hot wire tester.
