A bulb flickered over Sim's head, but didn't quite flash.

The bulb in the ceiling flickered, and we waited.

A second later the bell began again, and the bare bulb in the middle of the room flickered into life.

The dim yellow bulbs in the ceiling flickered by overhead.

The failing fluorescent bulb was flickering slowly, like a dying man's pulse.

He clicked it down and a few bulbs flickered into hesitant life.

If all those little light bulbs were flickering, going on and off without any order at all, we couldn't read the word, could we?

The long bulbs flickered but didn't immediately catch because the starters were bad.

A light switch was flipped and bare bulbs flickered to life.

He looked up as the light bulb flickered and dimmed, then sprang back to life again.
