A cigarette lighter adapted to function also as an aroma generator. The lighter is insertable into a socket in the dashboard of an automobile, the socket having terminals connected to the vehicle battery. The lighter includes a case that fits into the socket and a spring-biased hollow plunger that is telescoped in the case. The plunger is formed from a cylindrical shell having a cage projecting from its open rear end and terminating in a ring serving as the plunger knob. Attached to the front end of the shell is a heater unit which, in the inactive state of the plunger, lies within the case. To activate the lighter, the user presses in the plunger to advance the heater unit until its contacts are engaged by the socket terminals, one of which is a latching bi-metallic element, thereby energizing the unit. The resultant heat which is transferred to the interior of the shell also acts to deform and unlatch the bi-metallic element thereby disengaging the terminals and causing the released plunger to return to its inactive state. Receivable within the plunger is a replaceable fragrance cartridge having a shank which projects into the shell interior, the shank supporting a heat-responsive, aroma-generating element that is activated by the interior heat to exude an aromatic vapor that is vented into the interior of the vehicle.
