Equus 3420 Simple to use test light that is computer safe.
It comes with a cigarette lighter adapter for in car testing, which worked well while installing a radio in my truck. Large battery cables are included for any testing that is required when testing underhood.
Equus 3420 A great idea that works great too!
This is a neat little tool whether you are a car audio installer, mechanic, or homeowner.
Most test lights require a known source of voltage or ground, and if you poke the wrong wire, they can apply a load to the circuit that actually damages it. This little guy solves those concerns and lets you know what you've got on each wire without damaging any expensive sensors or components. You just plug it into the cigarette lighter or clip it on the battery posts and away you go. The LEDs are bright and easy to see, so it's a breeze to use.
Equus 3420 Very nice test light with a good grip, and bright LED indicators.
This test light has 3 colors: white, red, and green. The white LED indicates that there is voltage going through it, and is useful to add a little light to the area that is being tested. The red LED is for (+), and the green LED is for (-). The brightness of the red LED will help indicate how strong the voltage of the circuit being tested is. This test light is computer safe which is a must for modern electrical systems. It has a built in cigarette lighter style plug that has an internal fuse, and an adapter for connecting the tester directly to a battery. An ordinary test light only indicates the presence of a (+) signal while this tester performs like a logic probe to indicate a ground signal as well. It has a very good ergonomic grip, and is recommended for anybody working on automotive electrical systems.
Equus 3420 Smart Test Works Great.
Cost way less then other test lights,. No problem with shipping. although I haven't used it yet, compared to other circuit boards this will work great.
