A lighter is a portable device used to generate a flame for various purposes, such as igniting cigarettes, lighting candles, or starting a fire. Lighters consist of a fuel source, typically butane or lighter fluid, and a mechanism to ignite the fuel and produce a flame.
Lighters have been an essential tool for centuries, with early versions using flint and steel to create sparks. Modern lighters are much more convenient and reliable, and they come in a wide variety of shapes, sizes, and designs. They are also relatively inexpensive and widely available, making them a common household item.
