Automotive Test Light with 3-48V LED Digital Voltage Display, Auto Circuit Tester with Voltmeter & Dual Color Polarity Indicate, Electric Test Pen w/Stainless Probe for Car/Truck/SUV Checker

I absolutely love this thing! Use it daily for identifying const and acc circuits for various vehicle installations. Sharp point that easily pierces wire insulation, clip on ground so you don’t need to hold another probe and easy to read measurements. Great little tool.

Nice to have voltage reading instead of just a light to indicate live circuit

Easy to use still need my multimeter but this is much easier for all the 12vdc stuff. So easy to read, just clip it to ground and then poke around with the probe.

Works great.Only downfall,the clip is poorly made,it literally fell apart about the third time I used it,but I wired up a 4mm banana plug to it and now I can attach either a wire probe or an alligator clip.Which made it more versatile for what I do.

This WINAMOO automotive test light gets a solid 5⭐ from me — it’s bright, responsive, and simple enough to use in tight spots under the dash or out on a job. I used it to trace a dodgy fuse and check circuits on the Escalade after a long shift; the probe is sturdy, the clip holds tight to grounding points, and the light comes on instantly without false positives. Size is handy for the toolbox, and it handled the dusty garage fine with no fuss. Who this is for: Mechanics, DIYers, and anyone who needs a reliable, no‑nonsense test light for quick electrical troubleshooting.

Finally used it last few days . I highly recommend anyone attempting to find an electrical issue in your vehicle. It’s a great buy. Wish I bought one years ago.

Grateful for any voltage. Nice device

I purchased this as an add on to my arsenal for testing car related items however I was pleasantly surprised that it also worked to test power from something plugged into an outlet to ensure it was generating the correct voltage. It helped me realize a power supply I was using was bad so I needed to replace it.

Muy prácticos

A terrific product.Thank you.

tres bonne affichage

Fácil de usar, específico en cuanto a la polaridad de la corriente (verde o rojo) y sobre todo indica el voltaje que llega al punto donde se prueba.
