A lighter is a portable device that produces a flame, typically used to ignite cigarettes, candles, or other small objects. Lighters come in a variety of designs and styles, but they all share the basic components of a fuel source, an ignition mechanism, and a flame. The most common type of lighter uses butane as a fuel source, and a piezoelectric ignition mechanism to create a spark that ignites the fuel.
Lighters have been around for centuries, with the first known examples dating back to the 16th century. Early lighters were simple devices made of tinder and flint, and they were used primarily for lighting candles and torches. In the 19th century, the invention of the friction match made lighters less necessary, but they remained popular as a more convenient and reliable way to produce a flame.
