True Mods 4-Way Flat Trailer Wiring Tester [Nickel-Plated Copper Terminals] [Male & Female] [Continuity Test] 4-Pin Trailer Light Wire Circuit Tester

Eliminate Down Time and Frustration

No need to go to an expensive repair shop to have you trailer harness checked.  Our easy-to-use circuit tester helps you quickly identify and fix problems with your trailer light circuit.  Simply plug it into the bumper connection or in-line between the tow vehicle and trailer, turn on the lights to be tested and check the LED lights on the tester.  The correct LED will be illuminated if the power and ground wiring of the tow vehicle is functioning correctly.  If the LEDs are not coming on?  Time to check the tow vehicle’s wiring.  What about if the LEDs are illuminated but the trailer lights still don't work?  Time to check the trailer wiring.  Quick, simple and effective. 

Heavy Duty Build for Superior Performance

Manufactured to exacting specifications, this circuit tester is built to last.  The rugged PVC plastic body is designed to be weather, corrosion and impact resistant.  Even in the small details, this circuit tester stands out from the crowd.  Like the convenient dust cover that protects the tester when not in use.  Small enough to fit in your hand, tough enough to get the job done right.

Peace of Mind Towing

Take this small lightweight tester wherever you go and drive with confidence.  Quickly test your lights before, during, or even after a trip.  Switching trailers?  Not a problem.  Test any 4-pin trailer even if you are in the middle of nowhere.
