Light barriers are objects you will encounter in your adventure set up in key locations. To go through them you will have to pay the amount of light indicated on the sign nearby. Some of them can also be opened by interacting with the sign if you have the Triangle Tattoo.
The more important light barriers in the game are the ones in the staircway in the Memorandum. You will need to unlock them all to reach the Heaven level and final challenge. To unlock the last one you will need five harvesting fingers.
