1A somewhat literary or old-fashioned word for "light" or "lamplight," close in meaning to あかり. It tends to appear in poetic or emotionally evocative writing, and suggests soft light — like a candle or paper lantern — more than modern electric lighting.

The lights of fishing boats dotted the harbor.
