12 Volt

CMTOOL automotive circuit tester integrates functions such as voltage measurement, bulb measurement, load voltage measurement with bulb, pulse signal measurement, load device measurement, and power supply polarity display. Features:➤ 1.【ABS Material & 45 Inch Silicone Wire & Bigger Alligator Clip】The test light is made of ABS material, which is moisture-proof, impact-resistant and has a longer service life; this automotive test light is specially equipped with a 45-inch silicone wire, which is resistant to high temperature; the test light has a larger alligator clip, which can clamp larger battery bolts or terminals; Two sharp stainless steel probes are used for piercing wires and inspecting hard-to-reach narrow areas.➤ 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.➤ 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.➤ 6.【24-Hour Service and 1-Year Warranty】We provide this CMTOOL test light with 24 hours friendly customer service and 12 months free warranty to ensure your shopping experience. We always put our customers first, if you have any questions about this automotive test light, please feel free to contact us! • Professional car test lightCMTOOL test light can quickly diagnose vehicle circuit problems and is a must-have tool for professional auto mechanics, electrical engineers, automotive engineers or circuit DIYers. When the electric pen is connected to an AC signal (5-30V), the frequency range can be estimated through the display of the digital tube. Real-time Voltage DisplayThe voltage tester has a special LCD screen, it will displayThe voltage isclear at a glance. With lamp beads, it is more convenient to use at night. Positive And Negative IdentificationLED lights prompt, quickly identify the positive and negative poles 3 Modes SwitchThere are 3 modes in total. The mode switch is operated by the physical buttons of the electric pen body. Press and release the button to cycle through the three working modes.Mode 1LED digital display and bulb work at the same time.Mode 2LED dgital display works, the bulb does not work.Mode 3LED digital display does not work,bulb works normally.
