There is no need to add useless complications to F1 cars. Just run the races so they do not go into darkness. Putting lights out on the wings would involve wiring so changing wings would be more involved and depending on wether the connecter came apart or if the wires broke might make the job impossible in a short time. Lights could also get broken with minor contact that would not require a wing change.
I do not know how small lights in the wings would provide enough light. I admit I am no expert. The ALMS cars have large lights of the size found on road cars.
I have also seen one light fail several times on AMLS cars.
Brake lights on formula cars has been discussed umpteen times over the years and rejected every time and not just in F1.
So we do not need a complex cure for a problem that rarely arises and in fact does not need to if the race start time was early enough.
OK Cosmic?
