Lights, camera, action:
Let there be light,
Let there be more light
Shining a light on the subject

Light bulbs and search lights,
Incandescent lights and iridescent lights,
Neon lights and laser light

The headlights on your car that illuminate the road,
The taillights watched by the driver behind you,
The lights on the highway billboards lighting up the exit signs
The traffic in the intersections managed by those traffic lights

Turning the lights on,
Turning the lights off

Streetlights in which you can see parked cars and garbage cans,
An actor reciting a monologue in the cone of a stage light,
A ship using a lighthouse to navigate a point

Ultraviolet light,
Infrared light

A woman sitting under a reading light with a book of poems,
A man screwing a light bulb into a lampstand,
Lights upon lights in the windows of the apartment buildings

Candlelight

The light that goes on when you open the refrigerator door,
The light that goes off when you turn off the television,
The dinner you can eat sitting under the kitchen light

Sunlight, moonlight, and starlight,
Light sockets, lighting fixtures, mood lighting, night lights

The light at the top of the cellular transmission tower,
The light above the operating table,
The light at the end of the tunnel

Warning lights and signal lights,
The lights along the aisles of the movie theatres

Christmas lights
