Abstract: This invention relates to cigar lighters of the removable igniting unit type. According to this invention the core of the knob mounted on the igniting unit is made of a material having the property of piping light. A lamp housing is mounted on the sleeve of the holding device over a side wall opening thereof. An electric lamp in said housing produces light to pass into the interiors of the shell as well as the core of the knob whereby the front of the knob is illuminated clearly in the dark when the igniting unit is in place on the holding device and the interior of the shell is well illuminated when the igniting unit is removed. Therefore, by the provision of the present improved illuminating means, a much increased degree of safety is provided for the driver who travels at high speed at night to obtain a light for his cigarette without slowing down.
