Import Car Horn — Buy in Bulk from Supplier in China

The car horn supplied by Diguang Automobile Parts Co., Ltd is a 12V DC automotive signaling device designed for universal fitment across passenger vehicles, commercial trucks, and aftermarket installations. It operates within a standard frequency range of 400 to 500 Hz, producing a sound output of 105 to 115 dB, ensuring audibility in urban and highway conditions. The unit is compact, with typical dimensions of 90mm diameter and 80mm depth, and is engineered for direct bolt-on replacement of OEM horns.

Constructed from ABS plastic housing with a zinc-plated steel diaphragm, the horn resists corrosion and thermal stress typical in under-hood environments. The electrical contacts use copper alloys for reliable current flow, while the integrated relay simplifies wiring for both 12V and 24V systems where an adapter is used. Standard automotive horns in this class meet IP67 ingress protection, and this model is compatible with SAE J86 and ECE R28 regulatory frameworks for sound emission and durability.

Primary buyers include automotive repair shops, fleet operators, and OEM accessory manufacturers sourcing reliable signaling components. The product is typically packaged in sets of two for dual-tone applications, with bulk cartons holding 50 units. Common trade terms for this category include FOB Ningbo or Shanghai, with lead times of 20 to 30 days after order confirmation. Buyers should specify voltage and mounting type to ensure compatibility with their vehicle’s electrical system.

Diguang Automobile Parts Co., Ltd operates from Xiaxue Industrial Zone in Hongqiao Town, Wenzhou, a region recognized for its concentration of auto component manufacturers. The company specializes in OEM and aftermarket parts, with a focus on electrical and signaling systems for passenger and commercial vehicles. Its facility is positioned within a 30-minute radius of Wenzhou’s port infrastructure, facilitating efficient export logistics.

The supplier’s profile indicates a harbor trust tier, reflecting basic verification of its business registration and operational address. While the listed response rate is currently at 0 percent, this may be due to recent onboarding or seasonal demand patterns. The company does not advertise specific certifications in its profile, so buyers are advised to request copies of ISO/TS 16949 or other relevant quality management documents during inquiries.
