2. Automotive Circuit Tester with Three Working Modes This auto circuit tester can choose to work with the LED digital display and the bulb at the same time (quick test mode), or both work independently (computer safe mode and bulb mode). Press and release the button to cycle through the three modes. On the electronic device, you can choose the mode in which only the LED display works, which can effectively prevent the ECU from being burned out by the current.
3. LED Digital Display & Removable Replacement Bulb The automotive light tester features a bright and clear LED digital voltage display, allowing you to quickly and accurately read vehicle voltage, making it easy to work even in dark or low light conditions. There is a high-visibility test bulb on the top of the electrical tester pen, which is universal with car bulbs and can be directly replaced. The brightness of the bulb will vary with the measured voltage.
4. Bidirectional Voltage Test & Frequency Prediction The heavy duty circuit light tester is also a bidirectional voltage tester. You can connect the large alligator clip or the auxiliary probe to the negative or positive grounding, and the two LEDs on the top of the digital tube of the electric test pen are used for polarity indication. The test light probe automotive can be used to measure injector signals, spark plugs, crankshaft sensor signals, etc.
5. Professional 5-30V Circuit Test Light The new multi-function test light circuit tester makes up for various shortcomings of the existing vehicle repair electric tester. The test light with voltage display integrates the functions of voltage measurement, bulb measurement, load voltage measurement with bulb, pulse signal measurement, load equipment measurement, and power supply polarity display. The power circuit probe tester is ideal for cars, trailers, vans, RVs, motorcycles, boats, and more.
