Low Air Pressure Alarm & Brake Light Switch for Yutong Buses | P/N: 3757-00037 / VK691-5538Z2

Product Description

A Critical Component for Uncompromised Brake System Safety.

In the demanding world of public and commercial transport, the integrity of a bus’s pneumatic brake system is paramount. Nanjing Dingguan Accessories Co., Ltd. manufactures and supplies this high-quality, dual-function Low Air Pressure Alarm and Brake Light Switch, an essential replacement part for Yutong buses.

This single, robust unit performs two vital safety functions. As a low air pressure sensor, it continuously monitors the vehicle’s brake system. If the air pressure drops below the safe operating threshold, it instantly triggers a warning alarm, alerting the driver to a potential brake system fault before it becomes a critical failure.

Simultaneously, it serves as a highly responsive brake light switch. Upon application of the brake pedal, it ensures the immediate and reliable activation of the rear brake lights, providing a clear signal to other vehicles and drastically reducing the risk of rear-end collisions.

Key Features:

Dual-Function Design: Combines a low-pressure alarm and brake light switch into one efficient, cost-effective component.
Direct OEM Replacement: Engineered as a perfect substitute for Yutong part numbers 3757-00037 and VK691-5538Z2, guaranteeing a seamless fit and function.
Enhanced Safety: Provides critical early warnings and ensures brake light reliability.
Durable Construction: Built to withstand the rigors of daily commercial use for long-lasting, dependable performance.
