7-Pin Round Plug Trailer/Caravan/Car Circuit Tester
This 7-pin round plug provides an accurate visual check via 6 illuminated LEDs to ensure there is power supplied through each correct circuit and that power from the source is active through the trailer plug and to indicate if there is a failure in the wiring on both towing vehicles and trailers/caravans etc.
Just plug the tester in the 7-pin socket/plug of the trailer, caravan, RV etc. and press the yellow button on the side of the tester.
