Works great and a great price! Highly recommend
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.

Quick, trustworthy test light for the shop or roadside
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.
