Boeing 777 and 787 Navigation Lights Don't Reflect on the Ground
This might just be a performance optimization
As we explained elsewhere we read every single post but we do not have the capacity to reply to each one of them. Posting it twice or three times in a row make it less likely for us to respond at all.
My response was this may not be a bug, this may be intentional design to keep the frame rate high. The navigation lights are not that bright compared to the landing lights and their light shining on the ground has zero impact on being able to fly and land the airplane. Thus it is very low priority.
