荣威RX5刹车灯开关7811C，汽车制动开关替换件。

If your car suffers from brake lights staying on, or rear lights not illuminating when braking, or cruise control cannot be set, the brake light switch contacts may be aging or sticking. Properly functioning switch sends brake pedal position to the ECU to illuminate brake lights and release cruise control, ensuring safe driving. This replacement is for Roewe RX5 (Roewe) and OEM 7811C; fits 2016-2022 Roewe RX5 models. Installation: disconnect battery negative, unplug the old switch, plug in the new one directly, ensure pushrod fully contacts the pedal arm and locks in place.
