Review on 🔌 2PCS Heavy Duty Automotive Circuit Tester: Premium Test Light with Extended Spring Test Leads & Sharp Piercing Probe by Troy Jennings

Bad design. The bulb sits on a spring, which is a good idea, but the rod it connects to to light the bulb when the pointer hits a hot wire falls sideways and has to be taken apart and reinstalled . There had to be a cavity for the end of the bulb to sit in, or a washer around the headlight to keep it centered on the stem. UPDATE NOTICE. I took a piece of 3/8 inch rubber tubing and made a washer/gasket that went around the center of the bulb and then stuck it in the handle and now it works perfectly. So this is definitely a factory design flaw that needs to be corrected as above. It works, but not that well. My last tester served me for 40 years. won't last a year if I don't fix their technical error
