a tiny rebellion against the dark, sold to children and kept by adults.
means A small, dim lamp left on through the night to soften the dark, typically in a child's bedroom or a hallway.
from A plain English compound of "night" and "light," both Old English (niht and lēoht), stitched together as words often are when a thing needs a name. The pairing itself is old — "night light" once meant the moon or stars, the natural glow that kept the dark from being total — long before it shrank into a candle by a bedside and later a low electric bulb.
