What color is displayed on the E/WD when the landing lights are extended?

When the landing lights are extended on the A320, the color displayed on the Engine/Warning Display (E/WD) is green. This green indication signifies that the landing lights are in the correct and safe position for use.

In the context of aircraft systems, colors are used to convey important operational information to the flight crew. Green is commonly associated with normal operation, indicating that systems are functioning as intended. In contrast, other colors denote various statuses or warnings; for instance, red typically indicates a serious issue that requires immediate attention, while yellow often indicates caution or that a system is not in the normal operating range. Thus, the green light confirms that the landing lights are correctly deployed and ready for operation, enhancing situational awareness during landing procedures.
