Automobiles may provide several 12 V receptacles that are intended only to operate electrical accessories, and which can not be used with a cigarette lighter. Car manufacturers may offer a cigarette lighter only as an optional extra-cost accessory. Usually, only one 12 V receptacle near the driver will be able to accommodate an actual cigarette lighter, with other receptacles designated as "12 V auxiliary power outlets '' which are not physically able to power a lighter.
