Conventional motorcycle halogen bulbs produce dim light, scattered beam and serious heat accumulation. Without effective heat dissipation, they burn out quickly. Many low-cost LED bulbs suffer poor light focusing, obvious glare and unstable chips, and some cannot adapt to wide voltage systems.
Our LIUHJG Motorcycle H4 LED bulb adopts 3-sided LED lamp beads with high-speed silent cooling fan. Aluminum alloy radiator achieves fast heat dissipation. Smart constant current chip ensures stable lighting. 12-80V wide voltage design, focused beam for long-distance clear vision. IP67 waterproof, direct H4 plug & play for motorcycle headlight retrofit & upgrade.

Based in Guangdong, China, we operate two independent brands — HJG and LIUHJG, covering differentiated market positioning for global motorcycle lighting demand.
The HJG brand focuses on mature regional agent markets, with stable classic lamp models, well‑verified quality and localized after‑sales support, widely trusted by long‑term distributors in Southeast Asia. LIUHJG targets global emerging modification markets, launching innovative dual‑color fog lights, dynamic flowing turn signals and new‑style LED headlights, designed for modern motorcycle enthusiasts across Southeast Asia, the Middle East, South America, North America and Africa.
With two brand lines, we provide flexible solutions for different clients: classic mass‑selling items for bulk wholesale, and trendy new modified lights for high‑margin custom business. Our products are exported worldwide, bringing reliable motorcycle lighting to riders in multiple continents.


We implement a strict full‑chain quality control system for every motorcycle LED lamp, covering raw material inspection to final shipment.
01 IQC Incoming Material Inspection We strictly check all incoming raw materials such as ABS plastic, aluminum alloy, LED chips and electronic components with professional testing instruments. Unqualified materials will be rejected before entering production, to guarantee stable basic performance of finished products.
02 Standard Automated Production Line Equipped with injection molding, die‑casting, SMT and assembly equipment. Each production step follows standardized working procedures. Our skilled workers monitor production status in real time to keep consistent product quality batch by batch.
03 Professional Waterproof & Sealing Test All finished lights pass independent waterproof chamber testing (IP67/IPX7). Simulate heavy‑spray and humid riding environments to verify sealing performance, avoiding short‑circuit failure caused by rain and fog.
04 Finished‑product Mass Inspection & Aging Test Every lamp undergoes long‑time power‑on aging test, brightness detection and function check. Defective items will be picked out manually and by machine before packaging.
05 Packing & Shipment Control Qualified goods are packed with individual color boxes and export cartons. We supervise loading and delivery, ensuring safe and intact products arrive at overseas destinations.
