While in certain new interiors there is a light_dae_brazier_320. You can open your inventory and click on it as if picking up an item. Doing so will delete the light and also make your character shine as if you were the light. I cant find anything in my inventory and the lighting effect on your character never seems to go away. It does not display as any "Light" spell effect.
One of these braziers can be found in Emmurbalpitu, Aisle of Dawn as an example, but its not the place where i picked up 4 of these lights (some cave west of Indal-ruhn i forgot the name).
