Description:
- Auto test pen is designed to detect the failure of low voltage circuit of transportation machinery. It can be used in the maintenance work of transportation machinery such as automobile, motorcycle, bulldozer, roller, etc. Used to detect power, ground and find shorts and breaks in wires handle brightly illuminates if circuit is good.
- Great electrical automotive tool for house & car fuses, low voltage light sockets & circuits. By connecting the flying lead to an earth (ground) reference and touching the screwdriver tip to various points in the circuit, the presence or absence of voltage at each point can be determined.
- Special long life diode,w/o heat during working comfortable and safety.Connected with heavy duty insulated alligator clip and extra length ground wire. Accidental contact with live wiring can result in an electric shock. For your safety, rubber gloves usage will protect you from getting effected from electric shocks.
Light indicator when live electric wire is detected:
Our lamp were designed to glow when measured 6-24v electricity connection is complete. Excellent instrument to locate shorts of wires or to test the drains in cars. If the light fails to light up, you know that the wire isn’t live.
Note:
Please use this test pencil inside the range of test.(DC 6V-24V)
The difference of the measured voltage will cause the light and shade of the luminous tube to be different, this is the normal phenomenon.
The test pencil sharp, please use caution, and place far away from children.

I don't even know how many test lights i own. I own one that only tests for positive that is digital and another that the alligator clip is way too small and another the tester bulb you can't see and maybe even a few more i am not sure but i was looking for something that tests both voltage and ground and not just one. I wasn't looking for something Snap-on quality just enough to get the job done and be done with it. I liked this because of the price and that was really about it, i glanced at the reviews but didn't really read a lot of them. I purchased this a Friday and received the Monday without Prime so i was happy. I think it wasn't until Wednesday i didn't get to actually look at the product or put it too use. So here are my thoughts about it.1. The alligator clamp is decent, it opens up some what large enough to clamp on a bolt to for voltage or ground but it isn't superior quality.2. The length of the cord isn't very long, it is only roughly 2 ft which isn't something you will be able to reach from one end of the car to the other like most test lights. In addition the quality of the cord is durable and seems that it hold up to some wear and tear over time but does feel quite cheap when you hold it.3. The tip of the pen is actually very sharp and has a good point to test a fuse for example. Just don't slip or you may just be your blood.4. I will just make this as a note that when the bulb lights up it is actually very bright. It is brighter than most test lights i have used. Just for anyone wondering it is an incandescent bulb and this can be disassembled.Overall i can say that it is a decent test light and works as it should. Is it the highest quality? No but what can you expect for the price. Would you rather pay $100 for a Snap-on that basically does the same exact thing? I wouldn't because if this one works why pay for an expensive one. Think of how many you can purchase to get one at a Snap-on price. It just isn't worth it in my opinion. Otherwise this way a good deal and i happy with it.

Easy to Test during DIY. Sure to have for the Car - used during the rear view camera installation & testing. The clip helps testing without much efforts and single handedly.

Light bulb was not lighting up when I first used it. I did a test on a 12v battery to make sure it was working before I put the tester to work. I took the tester a part and realized the bulb was not making good contact with the terminals. After I reinstalled the spring and bulb, I tested again and then the bulb lit up.

Light works great. Find your ground, touch a power source, it lights up. Very sharp, easily penetrated wires to test for power. The rubber grips on the spring clip for the ground immediately slide off, so I will have to find an adhesive that keeps them on, but other than it works fine for the money.

bought two of this testers because they were advertised as 6,12,24 volt. waited over 3 weeks and when I used them on a 24 volt system , the bulbs blew out. took the bulbs out and they were rated for only 12 volts. very dissatisfied with this product. false advertising. don't buy this product.
