This is a simple flashlight bulb attached to a battery.

The light was the illumination from a photographer's flashlight bulb.

Then he took out his tiny makeup kit, with its mirror cover and a very small flashlight bulb.

You can put a flashlight bulb in series with the battery and bowl.

He pressed three and watched as the flashlight bulb lit up.

I've never seen anything in that crystal ball except the light from the flashlight bulb in the wooden base.

Electric current from a dry cell was routed through the rotary switches to light one or more flashlight bulbs.

With a flashlight bulb this usually requires two dry cells in series (about 3 Volts).

The darkness was almost complete: only a series of small red lights the size of flashlight bulbs glowed in the ceiling.

I wrapped the copper wires at one end around the flashlight bulb and taped it in place.
