Great product, well made, great quick diagnostic tool
Style: Circuit Tester
Great tool I use it all the time. tool helps you to quickly pin point whether there is a issue from the truck or trailer side of the lighting electrical system. Compared to my co-workers snap on version only obvious difference was a snap on logo and the significantly different pricing. Have had many truck drivers and other mechanics tell me they have never seen such a tool. Most of which say they are going to get one now. Have had it for a few months now and use it almost every day, so far it has held up. still looks brand new with no issues in functionality. ... show more

AWESOME MUST HAVE IT
Style: Circuit Tester
Great tester is a plus to have it on your big rig if you’re a truck driver OTR You’ll save a bunch of of time just plug in and you can see what line is out or if is on your tractor or trailer or if it is your lights cable I really recommend to have it handy

A Must Have, but one big caveat to consider!
Style: Circuit Tester
Review Image by J. Voigt J. Voigt
First off, this is a great tester. I've boughten two of these now since 2022. The first one, the right turn signal LED just stopped working. Hint - keep the broken parts, and I'm here to tell you why. You can make two bad testers into one good one. The circuit board is like a waffle slip-in part. The pins are molded onto the casing. One or the other goes bad. If you read vsrious reviews, you'll find that if you momentarily tug this tester sideways with the pigtail connector, these pins just shear off like tinsel, and you'll hear ping, ping, ping....as the pins just fall to the ground, your eyes wide!! How does this happen = obviously when you're working on the traiker and opening the pigtail receptacles trailer access panel or the area behind the receptacle to pull out the wiring, you're gonna have to pull the truck ahead....but at a truck stop, you can't do that, so you park the tractor beside the traiker, but stretch the pigtail to the pulled out receptacle and twist and bend wiring splices till you find the bad connection or repair...the coiled pigtails are the worst ones because they cause a springlike tension. This style of tester has really small pin connections at the base (JUST LOOK AT IT SIDEWAYS). You may never have a problem with them, until the day you use it like this doing a lights test, and using the tester like I explained to watch for the flickering light while messing with the wiring on an elusive lighting issue. That's why I gave it 4 stars. It's a must-have and a convenience for doing just this, but it has the darndest Achilles Heel as it snaps the pins off like this. So keep that in mind - to never do this!! Otherwise I love this thing. Every Trucker should have one, and they should even sell them at Truck Stops. You'd think DOT would promote these things, but then again we're truck drivers and we take what we can get as over(underpaid) slaves. Good luck and hope you buy one! ... show more

Such a good addition to have in hand to figure out what’s going on with the power from the truck or the wire or even the trailer.
