MRCARTOOL P50 Automotive Circuit Fuse Trailer Wiring Continuity Tester Digital LED Circuit Tester

【Unique Design & Easy to Use】Automotive circuit tester design, with a large alligator clip and two sharp stainless steel probes, one-handed operation, it can detect hard-to-reach narrow areas and puncture lines. The test light adopts special housing, mini size, durable ABS material, high quality 45 inch (about 114.3 cm) silicone wire, strong and heat resistant, high tensile strength. You can take this mini light tester with you anytime, anywhere.

【LED Digital Display and Bidirectional Voltage Test】The light tester is equipped with a bright LED digital voltage display, which can read the voltage accurately and quickly, and can be clearly seen in day and night. Connect a large alligator clip or a second probe to negative or positive ground, red light for positive polarity and green light for negative polarity.

【Three Working Modes】Electric test pen design with switch and 12V 5W test bulb, you can easily change the working mode you want. You can choose an LED digital display while the bulbs work simultaneously, or either, to test voltage and accurately diagnose a faulty battery or fuse circuit. Brightness can be changed by measuring voltage. The higher the voltage (30V max), the brighter the bulb (5W max).

【Replaceable Test Bulb and Predictable Frequency】The 12V test light has a 5W replaceable test bulb on top for high visibility and long service life. The light bulb can quickly detect a short circuit/broken circuit. This bulb is compatible with car bulbs, so it can be replaced directly. At the same time, when the LED light tester is connected to the AC signal (5~30V), the frequency range can be predicted, it is used for the fuel injector signal, spark plug, crankshaft sensor signal, etc.

【Wide application】Professional 5-30V circuit test light, widely used in DC voltage tester, car fuse tester, car battery tester, probe tester, suitable for all kinds of cars, trailers, trucks, recreational vehicles, motorcycles, boat etc. A car test light is a very useful tool for home, car engineer, electrical engineer, circuit DIY.
