Auer Signal obstacle lighting – visible safety at every height!

Obstacle lighting – Auer Signal RDMOLThe RDMOL series from Auer Signal sets a new standard in reliable obstacle lighting. These compact and robust signal lights ensure excellent visibility of tall structures such as buildings, cranes, masts and wind turbines.

Durable design

The lights are ruggedly built and feature modern LED technology. This provides a long-lasting, low-maintenance solution wherever safety and visibility are critical, for example in marine & offshore applications.

In line with international standards

The RDMOL obstacle lighting series complies with international ICAO and FAA guidelines for low-intensity Type A, B and E obstruction lighting. These standards define the lighting requirements for tall structures to ensure air traffic safety. According to these standards, RDMOL low-intensity lights may be used up to a height of 45 metres. This makes the RDMOL series a reliable choice for industrial applications such as tall chimney stacks.

Optimal performance

Thanks to energy-efficient LEDs, a weather-resistant enclosure and a high protection rating, the RDMOL series delivers optimal performance even in harsh conditions. Your installation remains visible day and night, with minimal maintenance costs and maximum safety.

Obstacle lighting designed for fixed applications and tough conditions

The RDMOL series is specifically developed for stable, non-moving applications. Think of tall buildings, cranes, masts and wind turbines that must remain visible 24/7. The durable aluminium enclosure and impact-resistant lens provide optimal protection against weather, wind and vibration. With the IP66 rating, the lights are completely dust-tight and waterproof, suitable for the most demanding environments.

Two versions

The RDMOL series is available in two versions:

  • RDMOL 110–240 V AC, suitable for fixed installations such as buildings or industrial sites.

  • RDMOL 24 V AC/DC, suitable for battery-powered use, for example in off-grid or emergency applications.

Types

The RDMOL series can be configured via a DIP switch to operate as low-intensity Type A, B or E obstruction lighting. Type A and B produce steady red light with a minimum intensity of 10 and 32 candelas respectively, while Type E is a flashing variant with a minimum intensity of 32 candelas. The lights deliver a bright, uniform 360° light signal with minimal maintenance needs and an exceptionally long service life, meeting the high standards of safety and reliability.
