Factory-Grade Precision.
Delivered at Scale.
A 10,000 m² purpose-built facility, 6 dedicated production lines, an in-house R&D team of 6 engineers, and an ISO-certified quality system -- built to serve serious B2B buyers across North America, Europe, South America, and Asia.
A Purpose-Built Facility
Designed for Quality Manufacturing
Our 10,000 m² five-floor facility is strategically organized to support every stage of manufacturing -- from raw material storage and precision assembly to laboratory testing and global shipment.
Five Floors, One Integrated Operation
6 Standardized Lines.
Consistent Output at Scale.
Each of our 6 production lines is operated by workers with over 5 years of hands-on manufacturing experience. Combined with ISO 9001 and TS16949-aligned processes, we deliver stable, repeatable quality on every run -- whether your order is 500 units or 50,000.
Production plans are adjusted based on your order timeline, spec changes, and custom OEM/ODM requirements.
Every line is led by operators with 5+ years of automotive lighting manufacturing experience -- reducing defect rates and rework.
Every production stage follows strict quality management protocols, from incoming material inspection to final pre-shipment audit.
6 Engineers.
Full-Spectrum R&D Capability.
Our dedicated engineering team covers the complete product development cycle -- from industrial appearance design and optical engineering to advanced electronics. This enables us to bring new models to market faster and tailor products to your specifications.
Industrial design expertise in housing geometry, lens aesthetics, and private mold development for differentiated product lines.
Circuit design, driver development, EMC compliance engineering, and power management for reliable performance under harsh conditions.
Beam pattern design, light distribution analysis, photometric simulation, and compliance with DOT/E-mark/SAE optical standards.
Majority of 600+ models feature proprietary molds -- giving buyers exclusive designs unavailable to competitors.
Engineering team works directly with buyers to adjust wattage, beam pattern, IP rating, or connector type per project requirements.
In-house support for E-mark, DOT, SAE, and CISPR Class 5 compliance -- from pre-testing to documentation submission.
11 Categories of
Professional Testing Equipment
Our ground-floor laboratory performs comprehensive validation across electrical, optical, mechanical, thermal, and environmental performance -- so every product ships already verified against international standards.
ISO-Certified Process.
Zero Compromise on Quality.
Our quality control framework follows ISO 9001 and TS16949 requirements at every stage of production -- from incoming raw material inspection through final pre-shipment audit.
All raw materials and components verified against approved specs before entering production
Ongoing inspection at each assembly stage to catch defects before they propagate downstream
100% of finished units undergo ≥1 hour automated aging test and full water immersion test
Visual, functional, and photometric check on 100% of units before packaging authorization
Random sampling inspection per ISO 9001 / TS16949 AQL levels before goods leave the warehouse
Every single unit inspected before packaging -- no sampling shortcut on final QC
Minimum one hour of continuous aging and water immersion per unit
ISO 9001 quality management + TS16949 automotive industry requirements
