About this item

  • Smart Mode : The professional automotive circuit tester defaults to SMART mode. Automatically senses between DC voltage, continuity and resistance testing without having to change any settings for the highest precision, making it easy to use
  • 0.8-100 V Wider Testing Range : Upgraded technology allows for measuring a maximum voltage of 100 V, outperforming the majority of auto electrical testers available on the market. Widely and perfectly for examining different vehicles’ electrical circuits, such as automotive headlights, taillights, faulty sockets, and fuse connections, as well as other 0.8-100 V DC wirings and circuits
  • Buzzing & Accurate Digital Reading : Buzzer sounds during continuity testing. 0.1 V resolution ratio with high accuracy. The test light with voltage display features a bright green backlight LCD digital display that provides accurate volt readouts, clear and visible for day and night
  • Quality Made & User-friendly : Our high-quality materials, unlike plastic test light bodies, are more secure to test. Its size and sharp test light probe are just right for tight areas like under the dash and a protective cover is attached to the coiled wire so you can protect against damaging things when you're done with it
  • Rest Assured to Buy : If durability is what you seek in a circuit testing tool, look no further. This digital test light comes with a nice little storage pouch to keep it in and a spare battery. And 3-year after-sales service and lifetime technical assistance are provided

Well, it isn't really a test lamp, it is a small voltmeter. I love the fact that it has a light, which helps out when testing and under the dash, especially to test fuses under there( why in the heck do car manufacturers put the fuse box in the worst locations?). This has a green back light, which is very pleasant. I used it to test dead flashlight batteries, as soon as I got it out of the package, so the voltage readout goes down to .4 volts. Only thing I don't like is the case, cases are always nice, but this case just needs to be a 1/4" longer so the tester didn't have to be forced and manipulated into fitting in it. Other than that it is a great little tool, and for $13 and change, I can't complain. Thanks. Kem. 8/22/24

Works as expected and helps a lot getting things done without a VOM so it saves a lot of space

The tester is super useful. I found one burned fuse and a couple of fuses with broken connectivity in my 20 y/o Acura. The tester made the check easy and fast. It took me just a few minutes. I've replaced the fuses and now my car audio and in-cabin lights work! :) Thank you, guys!

I read ALL reviews. Out of the box, the ground clamp sleeves were slipping off. So, I improved this by adding black and blue heat shrink. Refer to my photo. The blue heat shrink being shorter acts as a “locking” collar over the black heat shrink. Note the fold back on the ground wire. I also moved the probe tip up the cable and since I was at it, put red heat shrink on the exposed shank of the probe. Moving the probe tip up the cable curl improves tip retention naturally due to the looped coil spring tension.This probe tester is for DC use only. Do not use it to test AC power in your home. I tested 1.5 volt, 9 volt, auto 12 volt and 24 volt batteries. The readings were fairly accurate when verified with my Fluke true RMS multimeter. The ohms readings were off but one would only use this probe to establish continuity. One would use the multimeter for serious, accurate, troubleshooting. This probe is a step up from the DC probes with the simple LED or incandescent bulb in the handle. I have one of those in each of my vehicles.Store this in your vehicle in the trunk but not in glove box. Heat in the car during summer can be excessive. Also remember to change the AAA battery once a year. If it leaks, it will make a mess on the pc board in the battery compartment. I do this at Christmas time for all battery devices including smoke detectors, CO sensors, battery powered clocks etc… easy to get into this habit once December rolls around.This unit is good value for the money. Comes with a zippered case. Multilingual manual, AAA battery. I wouldn’t leave my expensive multimeters in my vehicles but with this price point and functions, this is a great little unit. The hold function is nice as well for those times probing under the dash connections don’t permit a viewing angle. So, overall, I’m pleased with this unit. Thank you.

Auf den ersten Blick sehr anständig und wertig. Eine Tasche für das Gerät ist auch dabei. Ich denke es wird voll und ganz seinen Zweck erfüllen.

Great product. The point is very sharp. For some use cases the point maybe too big such as interior fuse box of car. You can use a safety pin as a work around. But
