This simple mod is for racing under moonlight for all circuits (except Estoril and Imola) if you are already bored with the game like me.. Some may already know how to do it. There is no streetlighting for most and air and track temperatures may not be correct. For Bahrain and Monaco, please refer to my other mods. Don't think I will do anymore day to night mod.
Make backups and replace files accordingly for circuits you want to change.
