Commercial Vehicle & Construction Machinery Electronics
150+ active models across four product families: power distribution, control modules, switches & sensors, and displays & HUD — built under one IATF 16949 quality system for heavy trucks, excavators, buses, agricultural and new-energy platforms.
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.

ExploreHow 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.
Power + CAN / J1939 backbone runs across all four layers — 12 / 24 V heavy truck, bus and construction-machinery platforms.
