Test Light - Extra LED
Simple and affordable tool that gets the job done. Very easy to use to test electrical circuits. The LED included either turns on red or green depending on polarity. It also includes a replacement LED. The alligator clamp is strong, but I do caution it is on the large side, so it may not be able to reach tiny spaces.

Excellently made! This is worth easily double the price
My buddy used this to to trouble shoot his bed liner lights. It worked flawlessly and was able to pinpoint a grounding issue that we would have never found without this test light!! Well worth the money! Very well made with heavy gage steel and a nice ground wire with a strong alligator clip! You really cant go wrong here!!!

Slippery small clamp
Works as described. My only grip is the clip to clamp on to the ground is hard to depress because the silicon that covers it is extremely slippery. Also the maximum opening for the clip isn’t that large so clamping on to 10 mm bolts is a bit of a challenge. It’s best to just slide the silicone out of the way to attach it to the ground.
