Horse Trailer Light and Electrics Tester
This product is a 12v Towing Socket Tester that allows you to Test for and Identify Lighting & Wiring faults
Test your tow vehicle electrics socket & circuit
Test your Horse Trailer or caravan plug socket & circuit
Simply either plug the unit into your tow vehicle black socket to test the vehicle or plug the trailer black socket into the other end of the unit, simple.
This will ensure that in the event of a dodgy connection or your tow electrics not working at all in an instant you will be able to ascertain whether it is the Tow vehicle electrics at fault or your trailer or caravan electrics.
The unit then goes one stage further and LED read out will also show you which wire is faulty, for example (right hand indicator, left brake light etc)
Without this you can spend £££'s at a garage or spend hours playing with wires and connectors trying to find out where the problem is and even trying to ascertain is it the car at fault or the trailer!
The unit comes boxed together with instructions.
