How do LED trailer plugs work?

The KT LED Trailer Plug can be used as any standard trailer plug however comes with the features of an inbuilt LED circuit tester. When wired to your car or trailer and power is applied through the circuit the LED light will light up and indicate that there is power applied through this circuit. The inbuilt circuit tester will check for Park Lights, Brake Lights, Service Brakes and Auxiliary.

If any LED’s fail to illuminate the tester will assist in determining where the fault is located. If a different LED illuminates to the circuit being tested then there is a crossed wired connection within the trailer plug.
