Thexton's Portable Trailer Light Tester has alligator clamps that allow it to be used with any power source (i.e. jump pack, battery). This product has an 8A breaker for circuit protection, allowing users to check the lights quickly by themselves without needed to hook the trailer up to a vehicle. It tests left and right turn signals, taillights, and brake lights. The product can also be used to test electric brakes, reverse lights, and auxiliary lights when used with the company's THX839 seven blade to four flat adapter. The tester is handheld and lightweight.
