ALLOSUN GK5225 Automotive Wire Piercing DC Voltage Circuit 6V / 12V Hook Probe Tester 59 Inch Cord with LED & Buzzer Indicator, white

Although I dont recommend using this if you are inexperienced, it worked great. The long probe is great for testing lights in hard to reach places. I recommend it to any professional mechanics tool box.

Really good

good troubleshooting tool no issues deploying airbags and easy to check wires with insulation

Circuit Tester is good

It does what its supposed to, but as mentioned earlier needs to be sharpened and tightened up. Once those are done, it works great!

Works as it should good tool.

Facil de usar

Wonderful

Good quality. The piercing option is great for inline checking. The noise buzzer is perfect. Much better than just a light. Quality tool.

Use it on my 1964 C10
