I al;ways kept it dark but
I had LEDs around at places like on smoke alarm next to a doorway, LED on various places for me to get a bearing in the dark, and I rarely turned on a light to walk through the house.
However most computers I built since 2001 have had LED fans and lights and clear sided windows, there's quite a bit of light and the 42" TV is on 24/7.
I have solid wood doors front and rear with "flip locks" on them (these took police over an hour to break once on a "concern for welfare" and actually they never broke, but the door itself did. My windows are at a less than convenient height and I put my cane in a spot it will get tripped over in the dark, and I'm not sleeping where anyone would think normal people sleep. Still,
my across the street neighbors sleep with their front door wide open unless it's below freezing, and there are 6 "neighbor dogs" who alert everyone if anyone is near anyone's house on our half the block, or even walks down this end of our street.
Where I used to live in Houston, I tore out around the entrance doors and reinforced the stud framing for over a foot of wood on each side, used the wrap-around metal braces that go around door edges for locks so doors don't split, used can interlocking door and jamb metal device to disallow prying/jamb spreading and sliding anything behind lock bolts to saw them etc.. .... only weakness was the "bump key" (Google or youtube it) but that's what "flip locks" are for at night. I used 6" screws in hinges and put a "peg" in each hinge that went into both the door and the frame ... I used longer than standard metal strikeplates with 6" screws on that side too.
Of course I secured windows better than average too and they were higher than standard windows with thorn bushes and cactus below them too.
Fliplocks are cheap defense against "bump keys" at night (I use longer screws to go into the studs instead of just the frame)
