It stabilises the power signal, ensuring a constant current supply to your trailer’s LED lighting, preventing annoying flickers or warning symbols on your dashboard.
Its robust construction and embedded Nite-Lite feature also make it practical for night-time towing, caravan connections, and regular trailer use in rugged outdoor conditions.
