Voltage Test Range - Compared with current circuit tester, car test light adopts advanced technology to increase the maximum voltage to 100v, while the maximum voltage of others is 48v; automatic circuit tester is a perfect tool for testing and troubleshooting, such as car headlights, taillights, faulty sockets, fuses. Support resistance and continuity measurement - vehicle light tester can also measure the resistance and continuity of wires and circuits, saving you a lot of time, so there is no need for an additional ohmmeter when testing our car. When testing resistance, the accuracy is ±1.2%, and the voltage should not exceed 250v; when the resistance does not exceed 50Ω, the built-in buzzer sound. Safety and Backlit Digital Display - You may not always be in a comfortable environment when working with your car, the circuit tester is equipped with an LCD backlit display, which is easy to read at any angle; lighting is a great advantage for this circuit tester, so dim environment not affect your test The probe of the test light is made of high-quality copper, which has better conductivity than stainless steel; the probe can easily pierce the wire or have a proper connection with the fuse on the fuse panel; or use it in small and hard-to-reach areas. The insulated protective rubber tip protects you from and avoids accidental injuries Easy to use - The high-quality cable with a maximum length of 78 inches increases flexibility and matches the length of your care. It comes with a large-sized copper clip for easy one-handed operation. A storage bag and an aaa battery are also included, Weight: 0.31526103466 pounds, Manufacturer: tiyao
