neon bulb

Bright gas light

A neon bulb is a small glass tube filled with neon gas that glows orange-red when electricity passes through it.

These simple indicator lights were common in appliances and electronics before LEDs replaced them: The neon bulb on the coffee maker showed it was still on.

Neon bulbs differ from neon signs, which use shaped tubes for decorative displays.
