Product description Automotive Test Light Automotive Voltage Tester

Professional car fuse tester with LED digital display for precise voltage checks. Features insulated housing for safety, 91\" flexible cable, stainless steel probes, alligator clips. Ideal for quick electrical diagnostics.

Dual Color Polarity Indicator Light

Simplify troubleshooting with the test light automotive’s dual-color LED indicators. When the probe contacts the negative pole, the indicator shows green. When the probe contacts the positive pole, the the indicator shows red.—no guesswork needed.

DC 5-120V Digital LED Circuit Tester

Our BENACES automotive fuse tester ABS-transparent shell minimizes glare, allowing safe, accurate diagnostics even in bright sunlight or tight engine compartments, accurate voltage measurements to 0.1V.

Extended Spring Wire Design

Automotive test light 91 inch extension spring steel wire has excellent elasticity and is able to quickly stretch and return to its original shape, the spring wire design not only saves storage space, but also dramatically increases the detection area of the fuse tester automotive.

• What voltage range and detection capabilities does this car fuse tester offer?

  The tester operates from 5-120V with an LED digital display for clear readings, supporting DC, AC, and pulse detection.

• Can this tool access hard-to-reach areas during diagnostics?

  Yes, it includes a 2.3M heavy-duty spring wire and sharp, corrosion-resistant probe to pierce insulation and fit narrow spaces. An oversized alligator clip secures stable connections for testing headlights, sockets, or broken wires.

• What automotive circuit problems can this LED digital test light detect?

  It can accurately detect the voltage abnormality of 12V/24V vehicles (e.g. battery loss), fuse blowing, line short circuit/circuit breakage, relay failure, etc. The LED digital screen directly displays the voltage value (accuracy ±0.1V).

• What are the advantages of a 91-inch extension cord in real-world repairs?

  Extra-long cable design: Convenient access to remote components such as fuse boxes and starter motors in the engine compartment; Alligator clips can be used to secure the grounding point, freeing up both hands to operate the probe.

• How to identify the positive and negative terminals of the test line?

  The red light on the car fuse tester indicates positive and the green light indicates negative. (When the probe contacts the negative pole, the indicator shows green. When the probe contacts the positive pole, the the indicator shows red.)

• Multifunctional Voltage Detection & Clarity: The BENACES car Voltage Tester fuse tester automotive combines a digital test light with a bright LED circuit tester for precise readings from 5-120V. Its LED digital display ensures visibility in all conditions, while the test light with voltmeter function supports DC, AC, and pulse detection. Perfect for cars, boats, and motorcycles, this tool’s ABS-transparent shell minimizes glare, allowing safe, accurate diagnostics even in bright sunlight or tight engine compartments.
• Long-Lasting Build & Safety First: Engineered with a chrome-plated probe and heavy-duty 2.3M/91” spring wire, this Car Circuit Tester is built to last. The ABS high-hardness casing resists wear, and the insulated grip prevents electric shock. Unlike traditional testers, Attaching with large crocodile clip for easy single-handed operation, which is boosting the efficiency, its LED test light system avoids circuit burnout with automatic protection, while the ergonomic design ensures secure handling during prolonged use.
• Smart Polarity Identification: Simplify troubleshooting with the test light automotive’s dual-color LED indicators. When the probe contacts the negative pole, the indicator shows green. When the probe contacts the positive pole, the the indicator shows red.—no guesswork needed. This fuse tester’s offerirectional design works flawlessly for both positive and negative grounding systems, making it ideal for automotive, marine, and motorcycle electrical systems.
• Extended Reach & Precision Tools: Tackle hard-to-reach fuses and wires effortlessly with the 2.3M heavy-duty spring wire and sharp, corrosion-resistant probe. This test light with voltmeter pierces insulation and fits into narrow spaces, perfect for diagnosing headlights, taillights, sockets, or broken wires. The oversized alligator clip grips terminals securely, ensuring stable connections during testing.
• User-Friendly & Versatile: Designed for DIYers and professionals, this digital led circuit tester includes clear safety guidelines: intermittent testing (≤3 seconds) prevents overheating, while its compact design stores easily. The LED circuit tester’s voltage adaptability (5-120V) and auto-dimming LED brightness cater to diverse scenarios, from low-voltage motorcycle batteries to high-power marine systems. Keep it away from children due to its sharp probe.
