Light in vesteria?

This isn’t a necessity or anything, but I feel like adding something like a light or lamp your character could carry on their back would make at least my game play feel a little more clean. As it is, some places in the Vesteria world get not unbearably dark but not a pleasing darkness either. This could also be adjusted by changing brightness at night but I just feel like adding a lamp would be a nice addition. (NOT A NECESSITY)
