I used the search, as well as checking the wiki, and didn't find any definitive answer on Fallout 1 lighting penalties to sneak/steal. Specifically, sneaking in a dwelling in order to access a bookcase or other container while being watched by an NPC that won't allow it. Are there assumed light sources in a dwelling, for example? If so, do they affect my chances? Any difference between night an day in general? That's 3 questions total. Specifically I'm just starting out again and want to filch from Razlo's bookcase next to his wife. Same question would apply to Steal.
