Anotations

Scope note:

Displays of lights intended to be seen primarily at night, incorporating candles, lamps, electric lights, or other types of lights. Illuminations display lights in a decorative way, arranged in artistic designs, and usually in token of festivity or rejoicing. For displays primarily featuring fireworks, use "fireworks (visual works)"; however, fireworks may be incorporated as a feature of larger illuminations.
