I think that now we have to keep an eye on lamps and street lamps that a fuel indicator of some sort would be nice. So that when examined it will tell you approximately how much fuel is left or how long the lamp, fire source ect will last. Can we get some GM's or DEV's to answer this as nobody has a clue on how lamps actually operate. Would be nice to see if tar or oil is being used. Which raises another question. If I filled lamp with tar and put oil in halfway, is it now full of all oil or all tar? or does the tar get used up and then the oil?
