Code:
obj/Items
    Candle
        var
            Owner
        Lit = 0
        icon = 'objects.dmi'
        icon_state = "candle"
        verb
            Use()
                if(Lit)
                    Lit = !Lit
                    icon_state = "candle"
                    usr << "You blow out the candle."
                    Owner = usr
                else
                    Lit = TRUE
                    icon_state = "candle_lit"
                    usr << "You light the candle."
                    Owner = usr

world/New()
    ..()
    spawn() Candles()

    Candles()
        while(world)
            sleep(10)
            for(var/area/Weather/w in world)
                world << w
            for(var/obj/Items/Candle/o in world)
                if(o.Lit)
                    for(var/area/Weather/w in view(4,o.Owner))
                        w.icon_state="dark2"


Problem description:
For my game, I have an area called "Weather" that is every where. During the day time, it's icon_state is equal to "dark0". During the night, "dark7". I'm trying to make a simple proc that will change the Weathers that are within 4 spaces of the candle's icon_state to be equal to "dark2". I have only tried using the method above, as I cannot think of another way it can be done. Any help would be appreciated.

**EDIT**
I've debugged some and it turns out that it treats the Weather as a single instance, instead of each being a separate instance.

If you want to do things the way you're doing them, the only solution would be to move the turfs near the candle to a new area. This is something that tends to get confusing really quickly. Here's a simple case, which may or may not work for you, depending on how you use the areas:

area
  Weather
  Illuminated
      
  
obj/Items/Candle
  verb/Use()
    Lit = !Lit
    if(Lit)
      for(var/turf/T in oview(src,4))
        if(istype(T.loc, /area/Weather))
          new /area/Illuminated(T) //does not actually create a new area if there's already an /area/Illuminated
    else
      for(var/turf/T in oview(src,4))
        if(istype(T.loc, /area/Illuminated))
          new /area/Weather(T)


The Illuminated area would switch between dark0 and dark2, and the Weather area would switch between dark0 and dark7.

Also:

I've debugged some and it turns out that it treats the Weather as a single instance, instead of each being a separate instance.

That's how areas work.

As with anything, look things up in the DM Reference before you use them.
