Following the update on Concorde’s model, the anti-collision lights have been once again incorrectly placed.
The red Anti-Collision lights were mounted in each wing, two in the leading edge and a third one on the tail cone, all of them flashing at a rate of between 40-100 flashes per minute.
The red and green Navigation lights were mounted in the outer leading edge of each wing and a white one in the tailcone.
Landing lights were in each wing root, supplemented by landing/taxi and turn off lights, that like the main ones, were retractable, but mounted in the nose gear doors. They retracted back into their positions after taking off to reduce drag and especially at supersonic speeds.
Hope this helps with making the lighting for Concorde as accurate as possible!
