I bought a test light thinking it could find a parasitic draw, but it gave me confusing results. Many people make this mistake, and it can waste hours of your time. A test light measures current flow, but it creates its own path to ground that skews the reading. This means a dim bulb might … Read more
FEAOXYO vs BENACES vs CrysGuard Digital Fuse Tester: Best 6V 12V 24V Tester? I’ve spent hours testing the FEAOXYO Test Light Automotive, the BENACES Automotive Test Light with its 5-120V LED digital display, and the CrysGuard Test Light 3-48V Digital Fuse Tester. Each handles 6V, 12V, and 24V DC circuits, but they’re built very differently … Read more
You might wonder why you need a fresh fuse in your test light every time you check a different circuit. This matters because a blown fuse can give you a false reading and waste your time. Each circuit in your vehicle has a specific amperage rating, and the fuse in your test light is designed … Read more
Tiny Pets 5-90V Digital LED Circuit Tester Review I was trying to diagnose a flickering taillight on my RV and got tired of guessing which wire was hot. That’s when I grabbed the Tiny Pets Test Light Automotive, 5-90V Digital LED Circuit Tester with Voltage Display and finally saw exactly what was going on with … Read more
ANCEL PB100 vs AWBLIN Power Probe vs Zzxker Circuit Probe: Best Advanced Diagnostic Tool? I’ve spent serious time with the ANCEL PB100, AWBLIN Power Circuit Probe, and Zzxker Power Circuit Probe to figure out which one actually helps you chase down electrical gremlins. The ANCEL PB100 packs a 40-foot cable setup and 4 test modes, … Read more
Feikenee 6-24V DC Circuit Tester Review I was chasing a dead taillight on my truck and needed a fast way to check for current without guessing. That’s when I grabbed the Feikenee Test Light Automotive, 6-24V DC Voltage Tester—it handles 6 to 24 volts DC and has a 39-inch wire with an alligator clip for … Read more
WINAMOO vs JASTIND vs VEHLIVE: Best LED Test Light for Fuse Testing? I’ve tested three popular LED display test lights for fuse checking: the WINAMOO (5-120V), JASTIND (3-48V), and VEHLIVE (3-70V). Each one promises accurate voltage readings and easy polarity checks, but they differ in voltage range and build quality. If you’re a DIY mechanic … Read more
It is important to understand why you must replace the fuse in your test light with a circuit fuse for protection. Using the wrong fuse can damage your tool or your vehicle’s sensitive electronics. In my experience, a standard glass fuse blows too slowly to protect modern computer modules. A circuit fuse reacts much faster, … Read more
My test light can only read down to 0.01 amps because it is designed for basic circuit checking, not for measuring tiny currents. This matters because it helps you avoid chasing phantom electrical problems that a standard test light simply cannot detect. Most test lights use a simple bulb or LED that needs a certain … Read more
You bought a test light expecting it to double as a continuity tester, but it does not work that way. This matters because using the wrong tool can damage sensitive electronics or give you a false reading. Test lights need a live battery source to light up, while continuity testers generate their own tiny current. … Read more
