WINAMOO 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

Works as advertised. Clear instruction easy to use and saved me $100’s over taking my bike to the shop. My starter solenoid failed and without the tester it would have been difficult to pin point the issue. Once diagnosed I picked up a solenoid for $15 and was back in business 15 minutes later.

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.

Arrived very quickly, perfect tool and worked as advertised.

WINAMOO Automotive Test Light with digital voltage display works as expected and does the job. It’s accurate enough for basic use and the display is a nice feature. That said, it doesn’t have a heavy-duty feel—the wiring feels more plastic than rubber, and overall build quality is on the lighter side. For occasional home use, it’s perfectly fine. I wouldn’t expect it to hold up long in a professional environment, and I could see the cable getting brittle over time if it lives in a toolbox. You just have to be realistic at this price point—it’s cheap, and it performs like it. I’d call it a 3-star tool on quality alone, but for the price-to-performance, it earns a solid 4 stars.

Worked great was just looking for a test light but found the voltage reading to be useful. The light is red not white which really didn't matter but actually I like at night or in low light.

Seems like a decent little test lamp. Reads the voltage, which is a bonus. Green light voltage going in one direction, red light- reverse polarity. Decent length curly cord. You could spend a lot more for one that might last longer, but you can’t beat the price for this thing.

Perfect fuse tester! I am a mechanic and I use it almost everyday for testing batteries and fuses and it never disappoints. I would recommend this to anyone looking for a solid battery and fuse checker on a budget. It's really all you need

This tool is fairly good. There display is easy to read and three process off using it is simple. This would be a buy again item.

Sirve y funciona bien
