What is the color of landing lights used in helicopter landing zones?

Landing lights used in helicopter landing zones are typically yellow or orange. This color is specifically chosen because it is highly visible in various weather conditions and against different backgrounds, making it easier for pilots to identify the landing area during both day and night operations. The visibility of yellow or orange helps to enhance situational awareness and aids in preventing mishaps by clearly marking the safe landing zone.

Additionally, the use of yellow or orange lights aligns with standard aviation practices which prioritize safety and visibility. In contrast, other colors may not provide the same level of visibility or could be confused with other signals, which highlights why the yellow or orange option is the appropriate choice for marking helicopter landing zones.
