The Youlai catalogue is organised into four product families for modern commercial vehicles: power distribution, control modules, switches & sensors, and displays & HUD. Each family is backed by in-house engineering, automated assembly and a shared environmental and EMC test lab.

Power Distribution & Fuse Boxes is the largest family in the range, with 24+ NBX models in production. OEM buyers can also use the dedicated manufacturer page for a factory profile and custom quotations.

How the four families work as one system

Power is distributed, control modules make decisions, switches & sensors provide the inputs, and displays report system status back to the driver.
