I've been trying to find info on this because I know I read about it somewhere a long time ago. I just got my white refurbished 2.2 GHz MacBook on Friday, and tonight I got my first good look at Apple logo and lid in the dark. There is light penetrating the lid's casing around the bottom left corner, near the logo itself, and in a few other places. Is this at all normal, aside from the fact that it makes sense with the white plastic? Can anyone else with a white MacBook confirm or deny this phenomenon? It's hard to capture with a camera, but I'll try to post pics.
