As she passed near the truck, a lamp came on in the fog.

A lamp on a table against the farther wall came on.

An outside lamp came on as she neared the front door.

As soon as the lamp in her office came on, she heard the bell ring.

The evening light was fading away to darkness and lamps were coming on behind draped windows.

Rebus found it, and two delicate lamps either side of the bed came on.

Two lamps came on in the room, one at each end of the sofa.

We looked wistfully at the transmitter but the green lamp hadn't come on yet.

I heard a click, and a little glow lamp came into being.
