Actually try reading the link I gave you. It's pretty much what you wanted, with objects giving off light, it's just a simple layer and effect trick. A video of said effect:

You could probably use some sort of variable, if you also wanted to toggle lights (such as for removing torches, or a more specific example, lighting things with the Lamp in A Link to the Past)

How can I place a ''dark'' tile on every tile of another tilemap

I think you could do the same with an additional tilemap? Just give it the layer properties like in the guide above and make any spots of light black on the extra tilemap? Or white, not sure, haven't fiddled around with this method yet, so it's just a hunch.

There's that, other than having one of a 'light object', and using multiple instances of it? Sorry, I'm trying to help you the best I can.

Ok thanks I will try to check that
