The SecoRüt 12 volt test beam is the perfect solution for quick and practical testing of the lighting and electrical functions on trailers. Equipped with a sturdy aluminium carrier, 5 m connection cable and double plug (7-pin and 13-pin), it is ideal for flexible workshop use. A particular highlight is the integrated fault simulation via two switches, which can be used to simulate specific faults on the right and left indicators. This allows control systems, test devices and trailer electrics to be tested realistically. Simply connect, test and simulate faults - the SecoRüt test bar saves time, reliably detects problems and is an indispensable tool for anyone who works with trailer electrics.
