7P Tester 12V

This plug tester is suitable for 7-pin plugs and sockets. You can easily check whether all functions of your trailer or caravan are working, both for the socket and the plug. This way, you'll quickly know where the problem lies and what needs to be replaced.

The LEDs make diagnosing a problem easy. This plug tester operates on 9-volt batteries (not included), which can be easily ordered. With this multifunctional plug tester, you can also easily test your trailer lighting and your car's power strip.

By using this plug tester, you don't need a car to test your trailer or caravan lighting. This makes it very easy and quick.

The plug tester tests the main lighting cable. The tester indicates this with a light; when the function is working, the light will come on.
