What is a common function of LED lights in aircraft electrical systems?

LED lights in aircraft electrical systems are commonly used to serve as indicators for various system statuses. This function is crucial for pilots and crew as it allows them to quickly and effectively monitor the operational status of different aircraft systems. For instance, LED indicators can signal whether a system is functioning normally, if it requires attention, or if it is experiencing a malfunction. The clarity and brightness of LEDs help ensure visibility in various lighting conditions, thus enhancing situational awareness.

While other functions, such as providing ambient lighting or enhancing cabin comfort, may also be relevant in certain contexts, the primary and most critical application of LED lights in an aircraft's electrical system is to give immediate visual feedback about system status. This capability plays an essential role in ensuring flight safety and operational efficiency.
