Anemometer towers, critical for measuring wind speed and direction, play a vital role in various industries, particularly in renewable energy. Given their considerable height, these towers pose potential hazards to low-flying aircraft. To mitigate these risks, it is essential to equip anemometer towers with appropriate obstruction lights, ensuring compliance with international safety standards set by ICAO, FAA, and CAAC.
Type A Medium Intensity Obstruction Lights
For effective hazard marking, Type A medium intensity obstruction lights (OBLs) operating on DC48V are recommended. These lights offer optimal visibility, alerting pilots to the presence of tall structures. Utilizing a DC48V system enhances the reliability and efficiency of the lighting setup, especially in remote or off-grid locations.

Three-Layer Obstruction Lighting
To maximize visibility and compliance with regulatory standards, a three-layer obstruction lighting configuration is recommended for anemometer towers. The placement of the lights is as follows:
1. **Top Layer**: A Type A medium intensity OBL is installed at the apex of the tower. This light marks the highest point, providing a clear indication of the tower's full height to aircraft.
2. **Middle Layer**: Another Type A medium intensity OBL is placed at the midpoint of the tower. This intermediate light enhances the overall visibility profile of the tower, ensuring it is noticeable from various angles and distances.
3. **Low Layer**: The lowest section of the tower is also equipped with a Type A medium intensity OBL. This light ensures that the structure is visible even at lower altitudes, further reducing the risk of collision.
