This listing is for a trailer/caravan and tow bar socket/plug checker. It will test both the trailer lights and the vehicle socket, and can test trailer lights without plugging the trailer into a car. It requires a 9V PP3 Battery (not supplied). Simple to use, plug into the vehicle and turn the lights on to test the tow bar socket. Connect to the trailer/caravan and press the yellow button to test the trailer/caravan lights. An easy to read LED display bank shows green/red lights to indicate a fault/pass for each circuit. Suitable for 7 Pin Plugs and Sockets.
