Review on IIT 16687 Blade Pin Tester by Ahmed Rowe

The problem with this tester is that the lights only shine on one side. When plugged into my truck, the headlights face down towards the bumper so the headlights are not visible. I have to use a mirror to see which lights are on. This may not be a problem for you depending on where your plug is located on your vehicle. The second problem I had with this tester is that one of the blades on the 7-pin end is inserted all the way into the back of the connector and doesn't make contact with my truck's connector. I disassembled the tester and stuck the blade all the way into the front of the fork like the others. The next time I used the tester, the same blade was pressed against the back of the fork again. This blade doesn't snap into place like it should. I have requested a replacement. I will update my review once I receive a replacement.
