1. General Rules and Application of Signal Lamps 
   Amber signal lamps are intended for vehicles that create a temporary hazardous situation, such as maintenance and service vehicles. Blue signal lamps are permitted exclusively for priority vehicles (e.g., police, fire brigade, and ambulance) and may only be used in emergencies.
   
   
2. Detailed Mounting Instructions for Signal Lamps 
   Bij de montage van signaallampen moet rekening worden gehouden met de hoogte, de zichtbaarheid en de bevestiging. Deze voorschriften waarborgen de effectiviteit van de verlichting en zorgen ervoor dat de installatie voldoet aan Europese normen.
   
   General Mounting Requirements 
   Signal lamps must meet visibility standards as outlined in ECE R65 and electromagnetic compatibility guidelines as defined in EMC R10.

• E-marking: All approved signal lamps must bear an E-mark, indicating compliance with European requirements.
• R65: This standard includes requirements for visibility, color, and intensity, ensuring that signal lamps are clearly visible from specific angles and distances.
• EMC R10: This standard ensures that lighting does not cause interference with other electronic systems.
  
  Placement and Height of Signal Lamps
• Height Requirements: Signal lamps must be mounted at least 2.5 meters above the ground to ensure maximum visibility, especially on larger vehicles. This placement prevents obstructions from other vehicle parts and ensures visibility from various angles.
• Visibility and Angle: According to R65 guidelines, signal lamps must be visible from an angle of 10 to 90 degrees up to a distance of 50 meters in the dark. Blue signal lamps should be centrally placed on the vehicle (e.g., on the roof) for optimal visibility from all angles. If cargo or vehicle parts obstruct visibility, additional lamps may be required.
  
  Class 1 and Class 2 Light Intensity 
  The light intensity of signal lamps is classified into Class 1 and Class 2:
• Class 1: Suitable for use in low-light conditions, with a lower intensity that provides adequate visibility in low ambient light. This class is often used for amber signal lamps that are visible at night or in normal conditions.
• Class 2: Designed for daytime use, with a higher intensity necessary for visibility in daylight. This class provides stronger intensity to ensure visibility under bright conditions, ideal for vehicles operating in sunny or challenging visibility environments. 
  
  Technical Specifications and Mounting Instructions
• Flash Frequency and Intensity: The flash frequency for amber lamps should be between 1 Hz and 4 Hz. For blue lamps, the light intensity must be at least 100 cd, as defined in ECE R65.
• Color Consistency: Amber lamps must meet color requirements for yellow-orange, and blue lamps must exhibit a specific blueness that is clearly visible, as defined by standards.
• Mounting and Stability: Signal lamps must be securely mounted using rust-free fasteners and withstand weather conditions. A minimum IP65 rating is required for water and dust resistance, providing essential protection for equipment exposed to harsh conditions.
• Cable Protection and EMC Guidelines: Wiring must comply with EMC R10 to prevent interference and ensure stable operation.

Summary: When Can You Use Signal Lamps?

• Amber Lamps: Activate only when the vehicle poses a potential obstruction to other road users (e.g., stopped along the roadside). Not intended for continuous use during normal driving.
• Blue Lamps: Exclusively for priority vehicles and only in emergencies to indicate priority on the road.

This document serves as a reference for meeting legal requirements and installation standards. AEB recommends using certified products and having installation performed by a professional to ensure optimal compliance with standards.

1. What is ECE R65?
   

The ECE R65 standard is a European directive that prescribes how warning lights, such as beacons, flashers, and other signaling products, must perform to be effective under various lighting conditions. This means that every product designed and manufactured by AEB is tested for visibility, light intensity, and light distribution, both during the day and at night.

At AEB, we see this standard not only as an obligation but as an opportunity to provide the market with high-quality signaling products that prioritize safety. Our products meet this standard to ensure that emergency services, commercial vehicles, and other vehicles can operate safely under different conditions.

2. R65 Class 1 – Reliability and Visibility for Standard Applications
   

Class 1 within the ECE R65 standard is intended for warning lights typically used during the day, where direct, intense lighting conditions are less critical. Products certified as Class 1 are clearly visible during normal daylight conditions, but their intensity is slightly lower than that of Class 2.

At AEB, we understand that reliable signaling is crucial, even under normal conditions. Therefore, our Class 1 products are optimized to provide a strong balance between visibility and energy efficiency. This makes them ideal for vehicles that occasionally use signaling lights and where continuous high intensity is not always required, such as transport vehicles, maintenance vehicles, and agricultural machinery.

3. R65 Class 2 – Extra Intensity for Demanding Situations 
   Class 2 within the ECE R65 standard provides extra brightness and visibility for situations where warning lights must perform under challenging conditions, such as bright sunlight or adverse weather. These lights feature a dual-mode function, allowing them to switch between day and night modes. This way, the intensity can be adjusted according to the environment, ensuring safe and optimal visibility without causing glare.
   
   For AEB, Class 2 products are not just an addition to our range but an essential part of our mission to improve road safety. Our Class 2 signaling solutions are designed for intensive use and are suitable for emergency vehicles, traffic management, and other critical applications where maximum visibility is essential. We thoroughly test and optimize these products to ensure they remain reliable, even in the toughest conditions.
