I don't know why they are looking for night races, maybe just because F1 and MotoGP are mainly followed in Europe and they will race in Asia...
Anyway it is too much dangerous for cars without lights, just think about what could happen with a blackout.... (try it on a highway at 130 Km/h switching off your car lights.... and consider a MotoGP or F1 running at 350 Km/h!!)
