12V Automotive Circuit Tester Probe - 4M Lead Test Light With LED & Buzzer For Continuity, Polarity, Ground & Short Finding

About This Product

Troubleshooting car electrical problems just got way easier. This is a professional-style circuit tester probe with a super long 4-meter (13-foot) cable. It works on 6V to 24V DC systems (so cars, trucks, motorcycles, boats). It has a bright LED light and a loud buzzer that beeps when it detects voltage or continuity. Use it to: check for power at a fuse or wire, find a blown fuse, test switches and relays, check if a bulb socket is getting power, trace wiring, find a short circuit, or test for a good ground. The red clip connects to battery positive, the black clip to ground, and you use the probe tip to poke around. It even has overload protection up to 7A. Much safer and more versatile than an old-school test light. A must-have tool for any home mechanic or DIYer dealing with electrical gremlins.
