Need to figure out why your car’s lights aren’t working or if a fuse is blown? This Goupchn P1958 Automotive Circuit Tester Kit is here to help – without the guesswork. It’s built tough but smart, with a bright LCD backlit screen that shows voltage readings clearly, day or night. The display gives you a precise 0.1V resolution, so you know exactly what’s going on in your vehicle’s electrical system (accuracy within ±0.2V). And don’t worry – it uses very little current, so it won’t fry sensitive wiring or electronics like old-school test lights sometimes do.
The tester itself feels solid in your hand, thanks to a durable acetate body that can take some bumps in the garage. The probe is made of sharp stainless steel, so you can pierce through wire insulation easily or poke into tight spaces under the dash. Plus, it comes with a handy 3.3-foot extension cable that’s flexible, heat-resistant, and oil-resistant – perfect for dragging around the engine bay. You also get a set of large alligator clips and a sheathed puncture probe to tackle different testing situations.
Use it on pretty much any 3–48V DC circuit in your car, truck, or even around the house. Great for checking headlights, tail lights, socket connections, fuse boxes, and more. Whether you’re a DIYer or a pro mechanic, this kit keeps things simple, safe, and reliable. Note: This is an international product, so packaging and instructions might differ slightly from local versions.
