Tungsten filament may be applied as a heating filament for electrical cigar-lighter, which is a common feature of automobiles and trucks.
The electrical cigar-lighter is powered by an electrical cigar-lighter, which is also known as cigarette lighter receptacle, cigar lighter receptacle or cigar lighter socket. While the cigarette lighter receptacle became a standard DC connector to supply electrical power for portable accessories used in or near an automobile.
With the decline in the popularity of smoking, automobiles may provide several 12V receptacles that are intended only to operate electrical accessories, and which cannot be used with a cigarette lighter. Car manufacturers may offer a cigarette lighter only as an optional extra-cost accessory. Usually, only one 12V receptacle near the driver will be able to accommodate an actual cigarette lighter, with other receptacles designated as "12V auxiliary power outlets" which are not physically able to power a lighter.
