flags 4 is the day/night switch, so yes they are, BUT, if you enter valo during night you can go to the photoshot place and turn the lights off, map's lights doesnt work like cars ones(even staying on the same flag), once they're loaded you need to "unload"(or simply reload) them so to make them turn off(basically if you press the light button it will turn off the lights for the parts of the map not loaded yet, which allows you to turn off car's lights and keep city ones, at least those near your position)
