This LED tester will test all vehicle and trailer lighting functions - sockets and plugs. The LED indicator will show any problematic connections.
The tester can be connected directly to the trailer. In addition, you can check the functionality of the socket in the vehicle, but this requires 2 people due to the pedal press.
Simple and quick - the end is with a 13-pin connector and the other end connected to the 13-pin socket of the vehicle. This 12-volt tester is easy to use and instantly shows a fault in vehicle and trailer wiring.
