EN 12368 Certificate Used in Traffic Lights

Traffic lights play a critical role in ensuring road safety, and therefore, they must be manufactured in compliance with high-quality, performance, and reliability standards. This is exactly where the EN 12368 certificate comes into play. So, what is EN 12368?

What is the EN 12368 Certificate?

EN 12368 is a standard established for the design, production, and performance of traffic lights and signaling systems in Europe. The abbreviation “EN” indicates that this standard is valid across Europe, and 12368 represents the specific number of this certificate. This standard includes all the requirements that must be applied to ensure that traffic lights, signaling devices, and other related systems are safe, efficient, and durable.

This standard covers a series of requirements and tests that define the visual, structural, and environmental performance of red, yellow, and green signal lights used in road traffic. It is specifically applicable to round signal lights with diameters of 200 mm and 300 mm, aiming to ensure their safe operation for both pedestrians and vehicle drivers.

Benefits of the EN 12368 Certificate

The EN 12368 certificate enhances the safety, performance, and quality of traffic lights while also providing significant benefits. This standard ensures:

• Safety: Clear messages are conveyed to drivers and pedestrians through the correct colors, brightness, and visibility of signal lights, thereby preventing accidents.
• Durability: Resistance to environmental conditions (temperature, humidity, vibration, etc.) is ensured, extending the lifespan of the lights.
• Standardization: It ensures that traffic lights used in different countries and regions meet a specific quality standard, achieving international compatibility.
• Official Approval: Municipalities and road management authorities prefer and often mandate products with this certification, preventing non-standard products from entering the market.
