VEHLIVE P100 Plus Automotive Circuit Probe Tester — 12V/24V Digital Voltage Meter with 40ft Cable & Angled Backlit Display

The VEHLIVE P100 Plus is a compact automotive circuit probe that combines a test light, digital voltmeter and active 12V/24V power supply with a 40‑foot cable and angled backlit display for diagnostics anywhere around a vehicle.

Designed from customer feedback, the P100 Plus upgrades everyday electrical troubleshooting with a brighter LED, larger storage case and extended reach while keeping an affordable price. It replaces multiple single-purpose tools by measuring voltage, polarity, continuity and voltage drop, and it can actively supply power or ground to components so you can verify faults without full disassembly.

How does the P100 Plus help find electrical faults quickly?

The unit combines visual, audible and digital feedback to help you pinpoint wiring problems, bad grounds and failing components fast. Instead of guessing or swapping parts, you can test voltage at a connector, activate a device with the built-in power supply, and confirm continuity in one pass.

• Digital LCD shows voltage and polarity readings instantly.
• Active 12V/24V supply lets you energize relays, motors, and lights.
• Continuity and voltage drop checks confirm wiring integrity.
• Audible beep and LED indicators speed troubleshooting in noisy shops.

Can I use it on different vehicles and in tight spaces?

Yes — the P100 Plus works with 12V and 24V systems found in cars, trucks, motorcycles and many off‑road vehicles. The probe includes a 40‑foot total cable (two 20‑ft extensions) and an angled, backlit LCD so you can reach and read test points under beds, inside engine bays or around trailers without moving the vehicle.

• Compatible with 12V and 24V electrical systems.
• Two 20‑ft leads provide a combined 40‑ft testing range.
• 15° angled LCD and top LEDs improve visibility in tight spaces.
• Protective carrying case keeps everything organized for mobile work.

Is the P100 Plus safe and durable for professional use?

The tester is built with overload and short‑circuit protection to protect both the tool and vehicle electronics during testing. Its metal probe is corrosion‑resistant and the ergonomically textured handle reduces hand fatigue, making the tool suitable for daily use in busy garages.

• Overload and short‑circuit protection to prevent damage.
• Wear‑resistant metal probe for long service life.
• Non‑slip handle for comfortable prolonged use.
• Bright LEDs and backlit display aid low‑light inspections.

What power and connection options are available?

Use the P100 Plus straight from a vehicle battery or plug into a cigarette lighter socket for quick, plug‑and‑play diagnostics. The design lets you choose a convenient power source and keeps the tester portable for roadside jobs or shop benches.

• Works via direct battery clip or cigarette lighter connection.
• Active power/ground output to activate components without rewiring.
• Clear audio/visual feedback for positive test confirmation.
• Included storage case keeps cables and accessories tidy.

Who is this for: the VEHLIVE P100 Plus suits professional mechanics, mobile technicians, fleet maintenance teams and hands‑on DIYers who need a single, reliable tool to diagnose 12V/24V electrical systems quickly. If you regularly test relays, motors, lamps or wiring and want an affordable alternative to much costlier professional probes, the P100 Plus delivers expanded reach, active power capability and rugged construction at a practical price.
