KEHIPI Upgraded Buzzer Automotive Test Light 3-72V

SKU CH-J7D0-HV4T4

A DC 3-72V bidirectional circuit tester with LCD voltmeter, dual-colour polarity LEDs, audible buzz codes, 140-inch PU spring lead and anti-lost probe cover

  • Overall width6.9088 in (17.5 cm)
  • Bidirectional testing with red or green LED polarity indication and distinct single or double buzzer tones
  • Wide 3–72 V DC range covers more vehicle circuits than typical 48 V or 60 V testers
  • Digital LCD voltmeter shows exact voltage for precise fault finding
  • 140 inch PU spring wire with sharp stainless probe and anti-lost silica cover reaches tight spots
  • Large alligator clip enables secure one-hand operation while probing

Upgraded Buzzer Test Light 3-72 V

The KEHIPI automotive test light checks DC circuits from 3 to 72 V with a built-in voltmeter. Red and green LEDs show polarity while single or double buzz tones confirm voltage direction. A 140 inch PU spring wire and alligator clip allow one-hand operation in tight engine bays.

For technicians tracing faults on low-voltage

Suits mechanics testing headlights, tail-lights, turn signals and fuse boxes across a wide DC range. Not for technicians who need AC mains measurement, high-voltage EV battery diagnostics or data logging capabilities beyond the audible and visual indicators provided.

3-72 V DC testing range

The 3-72 volt span covers most automotive and light commercial circuits, exceeding common 48 V and 60 V limits. Buyers must verify their system voltage falls inside this window; the tool cannot safely measure outside it.

Questions about this item

What vehicle electrical system does the 3-72V range cover that a 48V or 60V tester would miss?

The 3-72V DC range handles 72V systems found on some heavy-duty or commercial vehicles, while 48V or 60V testers stop short of that upper limit.

Does the 140-inch spring wire reach across an engine bay while the alligator clip stays on the battery?

Yes, the 140-inch PU spring wire is long enough to stretch across most engine compartments while the large alligator clip remains clamped to the battery terminal.

How do I confirm the tester shows the correct polarity on a known circuit?

Connect the clip to ground and probe a positive wire; the LCD should read voltage, the red LED lights, and a single buzz sounds — reverse the clip to positive and probe ground for a green LED and double buzz.
