For the record, I turn on a salt lamp every evening. It provides a very soft, low level (think almost romantic, eh) of ambient light in the main space which includes any and all access routes to my MBR which is blacked out. Anyone in that space will be back lighted.You'll give away your location if you do. LOL
I get up at night all the time and the ambient light from my stove light and a night light with in my living room is enough for me to see everything.
Do people live in catacombs?
I hate to get caught agreeing with Blaster (again) but the damn guy just makes sense... :-)
