Universal Wiring Kits with NSL Deactivation – controlled switching of rear fog light

Are you looking for a **universal wiring kit that allows deactivation of the NSL (rear fog light)**? At Weltmann KFZ-Teile, we provide modules specifically for this purpose — ideal for vehicles without built-in NSL, conversions, or in cases where deactivation is legally or electrically required. These units are versatile and ensure proper circuit behavior.
