Here is the ultimate compliment to your Power Probe circuit tester. The accessory kit contains four products: a 20 ft. extension lead that gives your Power Probe the extra length you need for working on trucks, RVs and extra-long vehicles; a cigarette lighter adapter that enables you to conveniently plug your Power Probe into a 12V cigarette lighter socket; an 8” tip which extends your reach areas suck as under dashes or firewalls; a protective case to store your Power Probe circuit tester and all of the accessories.
