Is there any way to make the torches and candles light a bigger area then normal I like playing it dark but the torches light doesn't go far enough.is there anyway to change that in the files maybe.

You sure can. Just make a mod that changes the light Radius of the lights you want to improve.

For example, the default Radius of a common Torch is 256.
Change it 500 and you'll notice a big difference. (over 700 would likely be too much, but you can experiment)
