The purpose of an obstruction light is to warn aircraft pilots of potential obstacles in their flight path. These lights are typically installed on tall structures such as buildings, towers, and wind turbines. The light's brightness and pattern are regulated by aviation authorities to ensure visibility and avoid confusion with other lights.

1> obstruction light for tower 

Tower<=45m uses a single light （YOL32）or a dual light（YOL32D） with low intensity at the top, which can be adjusted to flash or steady on.

45m<Tower<=90m Use two or more low intensity A or B type single fixed Aviation obstruction light to provide stable combustion lighting in the middle layer, and provide medium intensity B or C (YML2000C)type obstacle lights in the top layer.

90m<Tower<=135m Use two or more low intensity A or B type single fixed obstacle lights to provide stable combustion lighting in the 1/3 layer,two or more low intensity A or B type single fixed obstacle lights to provide stable combustion lighting in the 2/3 layer, and provide medium intensity B or C type obstacle lights in the top layer.
If all fixed devices on obstacles need to flash synchronously with the universal flash rate,this regulatory requirement can be met through appropriate control and monitoring systems, which provide communication for critical system failures or lamp failures.

2.   Red obstruction light for high biulding

A high building aviation obstruction light is a type of aviation warning light used to indicate the presence of a tall structure that could pose a hazard to aircraft. These lights are typically installed on buildings, towers, chimneys, or other elevated structures that exceed a certain height and are located near airports or flight paths. The purpose of the obstruction light is to make the structure more visible to pilots, especially during low visibility conditions such as fog, haze, or darkness. The light may be steady or flashing, and may have different colors depending on the type of obstruction and its location. Some lights are also equipped with sensors that can detect the ambient light level and adjust the intensity accordingly. The use of obstruction lights is regulated by national and international aviation authorities, and failure to comply with the requirements can result in fines or legal action.
 Solar energy AC/DC can be used,We control monitoring by control boxes or APP (please see our YSHD).

3 .obstruction light for Wind turbine

 
the use of aviation obstruction lights is an important safety measure for wind turbines. By making these structures more visible to pilots, we can help to ensure that they can continue to generate clean energy without posing a risk to aviation.
Solar independent obstacle lights are suitable for low intensity lighting obstacles, but the application is temporary and/or there is actually no suitable power supply. Each independent solar lamp is equipped with an integrated solar cell system, and the solar modules provide autonomous operation and charge the internal batteries during the day. Conversely, batteries can operate in harsh solar environments without the need for expensive cables or generators. Solar obstacle lights comply with FAA and ICAO standards. Can use APP monitor.

 Hight<=45m, YSL10 or YOL32 low intensity on the top.

 45m<Hight <=105m YML2000C medium intensity aviation obstruction light on the top,YOL32 Low or YML2000C in medile level.

  105m< Hight<=210m YML2000C medium intensity aviation obstruction light on the top,YOL32 Low or YML2000C at 3/4 level.YML2000C at 2/4 level,YOL32 at 1/4 level.
