Description
This tester is suitable for both 13-pin and 7-pin plugs and sockets. It lets you easily check whether all functions of a trailer or caravan work – on both the socket and the plug – so you quickly find the fault and know what to replace.
LEDs make diagnosis easy. The tester runs on a 9 V battery (not included). With this multifunction tester you can test both your trailer lighting and the socket on the car, and you don't need a car to test the trailer or caravan lights – quick and easy.
The tester checks the main lighting cable: when a function works, the corresponding light comes on.

Not included: 9 V battery
