Understanding Intensity Obstruction Lighting: Types, Standards, and Applications
Intensity obstruction lighting is a key component of aviation safety systems used to mark tall structures that may pose a risk to aircraft. These lighting systems vary in brightness levels—low, medium, and high intensity depending on the height, location, and importance of the structure. From telecom towers to skyscrapers, obstruction lighting ensures visibility in all conditions. In this guide, you’ll learn about intensity obstruction lights, their types, regulatory standards, and how to choose the right system. What is Intensity Obstruction Lighting? Intensity obstruction lighting refers to aviation safety lights installed on structures to make them visible to pilots. The term “intensity” defines the brightness level of the light, measured in candelas, which determines how far the light can be seen. These systems are also known as: Obstruction lighting systems Aircraft warning lights Aviation obstruction lights They are required for structures such as: Communi...
