3-48V Automotive LED Voltage Tester with Polarity Indicator

-- THIS PRODUCT CONTAINS 1 TEST LIGHT PER PACK --

Quickly diagnose electrical problems with this Automotive Test Light, featuring a clear LED digital voltage display and dual-color polarity indicators. Designed to work across 3V to 48V DC systems, it delivers reliable voltage measurements and identifies circuit polarity in automotive, marine, and industrial applications.

The built-in voltmeter displays precise readings with 0.1V resolution, while the red/green LED polarity lights indicate positive or negative voltage instantly. A sharp stainless steel probe easily pierces wire insulation, and an anti-loss protective sleeve keeps the probe secured during storage.

The 96-inch extended spring wire and large alligator clip provide excellent flexibility and single-handed operation, making this an essential tool for checking headlights, tail lights, sockets, fuse connections, battery voltage, and alternator outputs.
