【Unique Design & Easy to Use】

The automotive circuit tester designs with a large alligator clip and two sharp stainless steel probes for one hand easy operation, it can detect hard-to-reach narrow areas and pierce wire. 

The test light has special shell, mini size, durable ABS material, a top-quality 45-inch silicone wire with sturdy, heat-resistant, high-tensile strength. You can take this mini light tester anytime anywhere.

【LED Digital Display & Bidirectional Voltage Test】

The light tester comes with bright LED digital voltage display and can read out volt accurately and quickly, can be clearly seen during the day and night. 

Connecting a large alligator clip or a second probe to either negative or positive ground, red light indicates positive polarity and green light indicates negative polarity.

【Three Working Modes】

Electric test pen designs with a switch and 12V 5W test light bulb, you can change working modes you want easily. 

You can choose LED digital display and the bulb work at the same time, or either of them works, to test voltage and accurately diagnosis faulty battery or fuse circuit. The brightness can be changed with the measured voltage. The higher the voltage(Max 30V), the brighter the bulb(Max 5W).

【Replaceable Test Light Bulb & Predictable Frequency】

12V test light has a 5W replaceable test light bulb on the top for high visibility and long life. Bulb can quickly detect the shorts/breaks of the electrical circuit. 

This bulb are universal with the car's bulb, so it can be replaced directly. Meanwhile, frequency range can be predicted when led light tester is connected to an AC signal (5~30V), it's used for fuel injector signals, spark plugs, crankshaft sensor signals, etc.

【Wide Application】

Professional 5-30V circuit test light, widely used in dc voltage tester, car fuse tester, automotive battery tester, probe tester, perfect for a variety of cars, trailers, vans, RVs, motorcycles, boats, etc. 

Test light automotive is a very useful tool for family, automotive engineer, electrical engineer, circuit DIY.
