Does what LED test lights cant
Impressed by the length, gauge and material of the cord and overall ruggedness of it. You can use this to check your ignition module by seeing how far the spark will jump from the plug wire, you can check both by distance and light brightness and you cant do that with an led type. These are best device for checking fuses in no time, hook the clip to gnd and on each fuse you will see a little tiny solder bump above each pin, just touch it with the ultra sharp point and watch the light. If your looking fo a blown fuse this is fastest way, go right down the line. I check 20 fuses in under 1 min. I've dropped this and banged it several times it wont break. Theres valid complaints on the crimping and soldering but com'on this id delivered to your door for 10$, how hard is it to fix a crimp or add some solder? Be careful the metal tip is a home defense weapon, this is hard hard metal and its razor sharp, it will easily cut deep into a finger or go straight thru you on a slip and fall. I have a large knife and gun collection but I ground down the tip for safety reason, Im sure you can put it right thru the hood or door/fenders on your car. Use it aw well to gnd othe light bulbs or coils, this can work just like a switch all the time and led types have problems doing that.

Excellent Tester!
First of all this tester works very well; better than I expected. It is great for checking continuity but can also be used to find shorts in a wiring circuit. It is great for troubleshooting problems and will be helpful when building wiring harnesses or adding to existing circuits. I really like the sharpened tip that can pierce wire covering when needed, or use to back-probe a connector. Second, the quality is better than expected. The wire cable and alligator clip are substantial and the see-thru handle is nice and thick. It even has a good strain-relief spring on the back end where the wire cable exits the handle. It reminds me of tools built 50 years ago when companies expected their products to last for decades. If it comes from China, it would really surprise me!

Perfect addition to your tool bag
Great little tester that I didn’t know I needed in my tool bag

Works Well for Price Point
This is a basic test light. If that is all you need this unit is built better than I expected for the price. It’ll be light duty use for me so no issues there.

Instructions
Clip to ground. I suggest using the negative pole on your battery. Probe a hot wire coming from the positive terminal of your battery. If the tester lights up, you have power to that point, where you probed. If not, then you have an open circuit. E.g. the fuse that the power needs to go through is blown, or your stoplight isn't lighting up because it's not getting power. If your test light lights up and your stoplight does not, then you have a bad ground for your stoplight. It's usually one or the other: no ground or no power. The test light helps to eliminate variables. Tip: Create an extra-long cable to clip directly to the negative on the battery, so you aren't relying on the car to be well grounded. Also: low voltage only, like cars -- 6-12 volt. Don't try it on the house current. That would be very, very bad. Test light uses 12 volt 3 watt automotive bulb. Higher voltage will fry the bulb (so even though it says somewhere that you could test 24v, don't try it!). 6v will work and be dim. 12v is just right.

Good quality
Mine broke after a million years had since I was Like 17 yrs old and iam 73 now Anyway I was surprised if the quality works Perfect Good price Better then at parts store So this should be a hand me down Heavy wire Ground is a little bit smaller than the other one But works Do recamend

Does what I needed it to.
I was hard wiring a radar detector to my truck and I needed something to determine a positive source. This is exactly what I needed. I didn't need to pay an arm and a leg for some voltage meter. I may use this a couple times, but for the purpose I would use it, it is more than sufficient. Pretty basic, clip to a ground source and then touch the probe to the terminal end of the wire, if the light in the handle comes on, it a positive source, if it doesn't move to the next wire. Pretty simple. I didn't rate durability because I've only used it the one time. I don't know how long it will last.
