Premium LED Bulb Automotive Circuit Tester, 6-24V Test Light with 135 Inch PU Extended Spring Wire, Sharp Hard Steel Probe Vehicle Circuits Low DC Voltage Light Tester

This is a great test light! As an A.S.E certified repair technician I use my tools on a regular basis. The test light I use at work I paid 75.00 dollars for it and it works great and bought the same one to use at home. It broke and needed one to use until I got it warrantied so I bought this one not expecting very much from it because it’s 7.99 really how good could it be. Well it’s just as good as the one I paid 75.00 dollars for I am very impressed and if my other one doesn’t get warrantied that’s just fine I won’t buy another one for the crazy price they want not to mention comes with a spare bulb thanks Winamoo for a quality tool for a reasonable price
