Genuine Original Product Rear Combination Light Tail Light for Yutong Bus ZK6122H9

The Part Number 4133-00077 is a left-side rear combination lamp widely used on large and medium-sized commercial coaches in China, primarily fitted on Yutong (YUTONG) bus models. As a critical component of the vehicle’s exterior lighting system, it integrates multiple signaling functions into a single robust housing. In 2026, this lamp remains a standard-fit or high-demand replacement part across major coach fleets due to its reliability, visibility, and compatibility with harsh operating environments. Designed for 24V electrical systems, it is available in both LED and halogen versions, offering fleet operators flexibility between performance longevity and cost efficiency. Its superior sealing, impact resistance, and optical clarity ensure safe operation under extreme weather conditions including rain, fog, snow, and long-haul vibration stress.
