Light bricks - good or bad?

I'm not sure if this has been discussed here before. But I've noticed some LEGO sets have a "light brick". As far as I can tell, these are bricks with a light and a battery in them. Sets with a light brick include "The Orc Forge" (9476), "Whitecap Bay" (4194), and it appears the new "Winter Village Cottage" (10229), among others. I don't have any light brick sets so I'm not familiar with them. My question is, does a light brick in a set effect the investment value at all? Is it a good feature short and long term? Is it possible for the battery to corrode/leak and damage the set, especially if stored for the longer term? Any comments? Similarly, I wonder if Power Function batteries (e.***. in Technic sets) can have a problem with corroding/leaking if stored for a long time.
