Introduction

WG971871002 is an original standard Electric Horn specially designed for SINOTRUK heavy-duty trucks, perfectly compatible with HOWO, A7 and other mainstream truck models. As an essential safety warning component of the vehicle electrical system, it is widely used for driving reminder, road warning and traffic safety prompting. This electric horn adopts high-quality pure copper coil and high-strength vibration diaphragm, featuring loud and clear sound, stable tone and low power consumption. With precision waterproof structure and integrated high-strength shell design, it can maintain stable working performance in various complex outdoor driving environments. Effectively replacing aging, silent or hoarse original horns, it provides reliable sound warning guarantee for heavy trucks during long-distance transportation and complex road driving, ensuring standard driving safety prompts.

Key Features

✅️OEM Exact Fit & Easy Installation: 

Manufactured strictly in accordance with SINOTRUK original factory size standards and mounting parameters. The WG971871002 electric horn features standard mounting holes, accurate wiring position and matching circuit voltage. It is a direct plug-and-play replacement part without cutting, drilling or wire modification, realizing fast installation and perfect compatibility with SINOTRUK heavy truck electrical systems.

✅️Loud, Clear & Stable Sound Quality: 

Equipped with high-precision vibration diaphragm and high-purity copper coil, the horn delivers loud, penetrating and non-hoarse sound. It features stable tone output without noise, stuttering or sound attenuation. The reasonable sound decibel design meets commercial vehicle safety standards, ensuring effective warning and reminding in highway, urban and construction site driving scenarios.

✅️Low Power Consumption & Energy Saving: 

Optimized internal circuit structure and high-conductivity coil effectively reduce operating power consumption. The horn works efficiently without burdening the vehicle battery and circuit system. It maintains stable sound output during long-term continuous use, avoiding circuit overload and power loss problems, adapting to long-hour operation of heavy-duty trucks.

✅️Excellent Waterproof, Dustproof & Anti-Corrosion Performance: 

Adopts fully sealed waterproof and dustproof structure with professional rubber sealing gaskets. It can effectively isolate rainwater, mud, dust and humid air intrusion. The metal shell undergoes anti-rust and oxidation treatment, with strong corrosion resistance and weather resistance. It will not fail or rust in rainy, snowy and muddy road conditions, ensuring long-term stable operation.

✅️High Vibration Resistance & Super Durability: 

The overall structure is reinforced and fixed, specially optimized for heavy truck bumpy driving environments. It has strong vibration resistance and structural stability, not easy to loose or deform under long-term vehicle jitter. With precise coil and diaphragm matching, it supports tens of thousands of sounding operations, effectively avoiding common faults such as sound distortion and silent failure caused by vibration.

✅️Wide Environmental Adaptability: 

Adopts high-temperature and low-temperature resistant electronic components, with a wide working temperature range. It can work normally in high-temperature summer exposure and severe cold winter environments, without sound weakness or failure caused by temperature changes. It adapts to all-weather and all-road heavy-duty transportation scenarios with ultra-low failure rate.

✅️Improve Driving Safety & Traffic Reminding: 

Powerful and penetrating sound provides effective traffic warning for overtaking, turning and driving on complex roads. It effectively reminds surrounding vehicles and pedestrians, reduces traffic safety risks, and solves the safety hazards caused by weak sound, hoarseness or failure of old horns, greatly improving vehicle driving safety.

✅️Strict Quality Control & Cost-Effective: 

All products pass strict sound detection, circuit stability test and waterproof durability test, fully meeting OEM and industry quality standards. With stable quality, long service life and competitive price, it supports retail and bulk wholesale, providing high-quality and cost-effective after-sales replacement parts for SINOTRUK heavy truck maintenance.
