Cigarette lighters are small devices designed to create a flame for igniting cigarettes, cigars, or other materials. They typically use a flammable fuel, such as butane, and can be operated with a simple push-button mechanism or a wheel that creates friction. Lighters come in various styles, including disposable and refillable models, and are often made from metal or plastic. The invention of the lighter dates back to the early 19th century, with the first practical lighter created by Johann Wolfgang Döbereiner in 1823. Over the years, lighters have evolved in design and functionality, becoming popular accessories for smokers and outdoor enthusiasts alike.
