Solar LED traffic warning sign with amber flashing LEDs, high-grade reflective film, >800m visual distance, 360H rainy-day working time, and custom shape support for road safety projects
Product Overview & Customization Capabilities
The Solar LED Traffic Warning Sign is designed for road safety, construction zones, traffic diversion areas, parking entrances, school zones and temporary traffic control points. It combines solar power supply, amber LED flashing, high-grade reflective film and a durable sign body to improve warning visibility without relying on continuous grid power.
The standard electrical system can be configured with DC6V or DC12V voltage and 2W, 3W or 4W LED power. LED spacing is controlled at less than 4.5cm to support a clear warning outline on the sign face. The flashing frequency is 40±2 times per minute, which is suitable for roadside warning, slow-down zones and temporary hazard notification.
The reflective film surface supports passive visibility when vehicle headlights illuminate the sign. The LED system adds active warning performance during poor light, rain, fog, night work and low-visibility traffic conditions. The listed visual distance is above 800m, which helps traffic safety buyers specify the sign for longer approach distances.
For OEM and wholesale supply, Xiamen Topmatched supports customized color, customized shape and project-based configuration. Buyers can specify sign size, warning symbol, LED color, solar panel power, battery capacity, mounting structure, reflective film grade and packaging requirement before sample or bulk order approval.

Quality Control & Certifications
Quality control for a Solar LED Traffic Warning Sign should cover electrical function, solar charging performance, waterproof structure, reflective film adhesion, LED spacing, flashing frequency, battery connection, sign body strength and packaging protection. The finished product must be tested as a complete traffic safety unit, not only as separate LED or solar components.
For bulk orders, buyers should confirm the LED flashing rate, LED color consistency and warning pattern visibility before shipment. The flashing frequency should remain close to 40±2/min, and the LED distribution should match the approved drawing. Any inconsistent LED spacing can reduce the warning outline and make the sign less clear from a distance.
The solar panel and battery system must also be checked. Solar panel wattage options include 17V/3W, 17V/4W and 17V/5W, while battery options include 12V/8AH, 2×12V/7AH and 2×12V/8AH. Buyers should confirm the final configuration based on installation area, expected sunlight exposure, rainy-day working time and project budget.

FAQ
How should buyers confirm the visual distance of a solar LED traffic warning sign?
Buyers should check LED brightness, reflective film grade, sign size, flashing frequency and installation height together. The listed visual distance is above 800m, but actual performance depends on road alignment, vehicle speed, weather, background light and the approved solar-battery configuration.
Can the warning sign shape and face design be customized for project use?
Yes. Shape, color, warning symbol, LED layout and reflective film surface can be customized by project requirement. Buyers should provide artwork, sign size, mounting condition, LED color, solar panel power and battery requirement before sample confirmation or bulk quotation.
Is the solar LED warning sign suitable for rainy outdoor traffic projects?
Yes. The product is designed as a waterproof solar LED traffic sign, with listed rainy-day working time of 360H. Buyers should confirm battery capacity, solar panel wattage, waterproof housing design and local sunlight conditions before approving the final bulk specification.
