These devices boost safety by using loud, customizable voice alerts and high-intensity LED lights to provide clear warnings in high-risk areas like power facilities or construction sites.

As a vital artery of modern transportation, highways handle enormous daily traffic volumes. However, sudden incidents such as natural disasters and traffic accidents continuously threaten driving safety. Traditional warning devices are limited to single-function alerts, either visual or auditory, with poor performance in adverse weather. A key drawback is their inability to support precise positioning and remote control, leaving drivers without timely and effective protection.
 

Chuangdi integrates both sound and light into its alert systems to enhance warning efficiency. When choosing an intelligent voice warning light, focus on the following 5 core aspects.

1. Dual Sound-Light Alert Effect
The alert effect of a quality intelligent voice warning light is evaluated by two core dimensions, namely light warning effect and sound warning effect.
Light Warning Effect
Light warning effect refers to the visibility and adaptability of the light signal in different environments. It is mainly determined by visible range, luminous intensity adjustability and stability.
High-quality models typically have a maximum visible range of 500 meters and 8-level luminous intensity adjustment (500–7,000 cd/m²). This ensures clarity in strong sunlight and low-visibility scenarios, while avoiding glare interference at night.
Sound Warning Effect
Sound warning effect denotes the ability of the warning sound to penetrate ambient noise. It is measured by sound pressure level and sound penetration performance.

For use on highways—especially under demanding conditions such as heavy rain, strong wind, or dense fog—a maximum sound pressure level of ≥128 dB is often required to ensure the warning is effectively conveyed through both traffic noise and adverse weather interference. Advanced models also offer adjustable tone patterns, allowing sharp, urgent tones for immediate hazards and calmer, rhythmic tones for general guidance, thereby improving the recognition accuracy and appropriateness of driver responses.

 

2. Intelligent Sensing and Diagnostic Capabilities
This capability determines the proactive protection and maintenance efficiency of the device, covering precise positioning and addressability, as well as self-diagnostic and collision detection functions.
Precise Positioning and Addressability
Precise positioning and addressability mean each device is assigned a unique identifier, enabling the command center to locate it in real time for targeted alerts and remote operation.
Self-Diagnostic and Collision Detection
Self-diagnostic and collision detection functions monitor the device’s operating status in real time, including power supply, communication and modules, to identify faults or damage immediately.
This feature reduces maintenance costs and downtime, as staff can carry targeted tools and avoid blind inspections across vast highway networks.

 

3. Operational Control Flexibility
Operational control flexibility reflects the device’s adaptability to dynamic highway conditions, including multi-mode operation, dual control methods and customized warning content.
Multi-Mode Operation
Multi-mode operation refers to the device’s ability to switch between different working modes, typically Standby, Traffic Guidance and Emergency Alert, via one-click remote control.
Dual Control Methods
Dual control methods include automatic and manual control. Automatic control adjusts warning levels based on sensor data, while manual control allows command center intervention for special scenarios.
Customized Warning Content
Customized warning content means the device can display scenario-specific messages, such as "STOP," "HAZARD," "SLOW" and "ICE," via built-in screens or projections.

 

4. Fault Tolerance and Reliability
Fault tolerance and reliability are key to zero-downtime operation, influenced by dual fault-tolerant mechanism, durability and environmental adaptability.
Dual Fault-Tolerant Mechanism
Dual fault-tolerant mechanism covers power supply and communication. Grid power with backup batteries ensures continuous operation, while combined wireless and wired communication prevents signal loss.
Durability and Environmental Adaptability
Durability and environmental adaptability depend on high-quality materials, which should be fireproof, UV-resistant and anti-corrosive to avoid damage from extreme weather.
IP65 protection is mandatory for outdoor use, ensuring complete dustproof and water jet resistance. It guarantees stable operation in temperatures ranging from -40℃ to 70℃.

5. Ease of Use
Ease of use refers to the convenience of interacting with the device throughout its lifecycle, including installation, and after-sales maintenance.
Installation
Installation convenience is determined by the device’s design. A modular structure and straightforward hardware enable quick installation on guardrails, poles or bridge piers, saving labor and time costs.
After-Sales Maintenance
After-sales maintenance involves the convenience of troubleshooting and part replacement. Easily replaceable modules, clear fault prompts and remote troubleshooting reduce high-altitude risks and costs.

 

Summary
It can be complex for businesses new to highway safety equipment to choose the right intelligent voice warning light. Beyond the parameters mentioned, consulting professional sellers for tailored advice is essential.
