Intent on making wind turbines less obtrusive, obstruction lighting providers continue to improve the technology.
A wind farm’s blinking red obstruction lights are a necessary safety measure to ensure wind turbines – which can measure from 400 to 550 feet in height – are visible to pilots and their aircraft. However, the intensity of these beams can also be an irritant to nearby residents, as the lights blink in contrast against the night sky. But thanks to advances in obstruction lighting technology, suppliers are introducing new products that flash only when necessary. The improvements are part of a growing trend to make obstruction lighting programs less intrusive.
