This is a great test light! As an A.S.E certified repair technician I use my tools on a regular basis. The test light I use at work I paid 75.00 dollars for it and it works great and bought the same one to use at home. It broke and needed one to use until I got it warrantied so I bought this one not expecting very much from it because it’s 7.99 really how good could it be. Well it’s just as good as the one I paid 75.00 dollars for I am very impressed and if my other one doesn’t get warrantied that’s just fine I won’t buy another one for the crazy price they want not to mention comes with a spare bulb thanks Winamoo for a quality tool for a reasonable price

This circuit tester appears to be a reliable and affordable tool for general automotive electrical diagnostics. It offers good value for its price and I love its ease of use and bright LED indicator. I personally upgraded from a rather old flashlight bulb type. However, users should be mindful of the potential for wire damage due to the sharp probe and the sometimes stiff clamp. If you are looking for a basic circuit tester to keep in your toolbox for everyday automotive electrical checks, this seems like a solid option. Pros: Easy to use and understand: Simple connection makes it user-friendly for both beginners and experienced individuals. Effective for troubleshooting, it effectively checks for continuity and helps pinpoint electrical issues. Bright LED light, The high-visibility LED bulb makes it easy to see when a circuit is live. Long and flexible wire: The extended spring wire provides ample reach. Durable construction: Seems well-built and sturdy. Good value for the money a worthwhile purchase. Cons: Limited Voltage Range: Only suitable for testing circuits within the 6-24V DC range. Potential for wire damage. The sharp probe requires careful use to avoid damaging delicate wires. Clamp stiffness: the clamp is a bit stiff and difficult to open, especially on circular surfaces. Springy cord can be inconvenient, The coiled wire can be a bit too springy, potentially pulling the clip off if not properly secured.
