The electronic flags supplement the traditional cloth flags which have proven hard to see at night and there will be 35 units all up situated around the track. The electronic units will be used in conjunction with a new lighting system to light up the track, making the race less dangerous and easier for drivers to adapt to the new environment. The system will be controlled by officials at each marshal's post, while the race director will be able to see what all the flags are displaying from a central control room.
The flag system is the result of more than ten years of testing and development meaning that it is certainly more complicated than it appears. Apparently it took this long because of harsh requirements established by the FIA. Developed by Italian firm Valerio Maioli, the system will be the first of its kind and should add to the surreal experience of watching a night-race for the first time.
