    Automotive Circuit Tester with 3-120V LED Voltmeter, Car Test Light Dual Polarity Indicator & Long Probe, Fuse Checker RV Marine Tool

    • [Wide-Range Digital Voltage Display] Built-in high-visibility LED digital screen supports 3V to 120V DC voltage detection. Unlike traditional test lights that only indicate presence or absence of power, this tester provides clear real-time voltage readingsdown to as low as 3Vmaking it ideal for testing sensors, control circuits, and a wide range of automotive electrical systems
    • [Smart Dual-Color Polarity Indicator] Integrated polarity recognition instantly shows red for positive and green for negative at the probe tip. The color-coded indicator allows for quick polarity identification, speeding up troubleshooting especially in complex wiring harnesses or tight spaces
    • [Extended Stainless Steel Probe] The long, durable stainless steel probe easily pierces wire insulation for direct contact testing or reaches deep into fuse boxes, relay sockets, and other confined areas while helping minimize the need for disassembly of interior panels or components
    • [Multi-Scenario Voltage Compatibility] With a 3V120V DC range, this tester works on 12V/24V cars, trucks, motorcycles, as well as RVs, marine vessels, and heavy equipment. From low-voltage sensors to high-current circuits, one tool covers a broad range of diagnostic applications
