This mod is a day-night race at Bahrain. I think it looks amazing. It does use the Stunning Singapore Day-Night Race mod aswell. http://www.racedepartment.com/downloads/stunning-singapore-day-to-night-race.1096/
I would also strongly recommend using the Anti-Flicker mod here: http://www.racedepartment.com/downloads/killing-the-flickering-bugs.1068/ . Because I had an issue with flickering at turn 13. Also don't forget to back your original files up!
I do also have a time lapse of the race coming soon I just need to find some time to upload it!
