Vehicles do not have any light inside the vehicle. And it is strange that in the daytime, the passenger seat of APC, for example Panther is too bright, you can see anything. But in the nighttime, you can see moonlight inside the vehicle! it is very strange! The passenger side of the APC is sealed area, so there will be no lighting source to illuminate inside(for now).So there must be lighting source inside the vehicle to turn on/off. {F21536}
