At the time, this was one of my favorite pieces of equipment. I actually constructed this circuit tester in the 90's, probably cost me $10 in materials. What made this unique was that it will distinguish a + or - circuit. When most test lights will just turn on the built in bulb. As far as I can remember I don't think there was anything equivalent. Now a days the power probe has taken over all electrical duties and this sits in the tool box.
