Import Auto Hid Conversion Kits (L/H Moving) — Buy in wholesale FOB from Supplier in China

Guangzhou Liancheng Technology Co., Ltd supplies Auto HID conversion kits with low and high beam moving functionality, designed for direct replacement of halogen bulbs in vehicles requiring dual-beam HID operation. The kits utilise high-intensity discharge technology with xenon gas-filled quartz arc tubes, producing approximately 3,200 lumens per bulb at a colour temperature of 6,000K, compared with 1,500 lumens from standard halogen equivalents. Input voltage operates at 12V DC through integrated ballasts with rapid-start circuitry, drawing 35W per bulb versus 55W for halogen, which reduces load on the vehicle electrical system.

The arc tube contains xenon and mercury salts in a quartz envelope rated for vibration resistance and thermal shock up to 800 degrees Celsius during operation. Ballast housings are typically sealed aluminium with potted electronics to resist moisture and road salt ingress, with IP65 protection standard for the ballast unit. Wiring harnesses use copper conductors with ceramic connectors at the bulb base to tolerate continuous heat cycling. Beam pattern control relies on a solenoid-actuated shield mechanism that physically moves to alternate between low and high beam distributions, maintaining optical focus within the original reflector or projector housing.

These conversion kits target automotive workshops, aftermarket parts distributors, and fleet operators in markets where night driving visibility and reduced maintenance intervals justify the upgrade cost. Installation requires compatibility verification against the vehicle's existing bulb type (H4, H13, 9004, or 9007 are common dual-beam applications) and physical clearance for the ballast and relay wiring. Buyers should confirm with Guangzhou Liancheng whether the supplied ballasts are CanBus-compatible for modern vehicles with bulb-out detection systems, and whether the kits include error cancellors or resistors as standard.

Guangzhou Liancheng Technology Co., Ltd is located at Room 2103, Qiaoshunlou, Guanghua Mansion, No. 84 Tianhe Bei Road, Tianhe District, Guangzhou 510510, China. The supplier holds an imported tier classification and a harbor trust tier within the marketplace, with no response rate data available and zero recorded average response hours. The listing does not state factory ownership, production capacity, year of establishment, employee count, or specific certification holdings for this product line.

The company profile as presented offers no verified client list, export volume figures, or documented quality management system accreditation. Buyers should independently verify manufacturing credentials, request ballast EMC compliance test reports, and confirm whether Guangzhou Liancheng operates as a trading office or maintains direct factory relationships for HID kit assembly. The Tianhe District address places the supplier in Guangzhou's central business district, which is consistent with trading companies that coordinate with manufacturing bases in Guangdong Province rather than always manufacturing on-site.
