An illuminating device includes an insulative housing, at least two electrodes and a light source. The upper unit forms a protrusion. In use, when the filter cigarette is placed in the mouth of a consumer, moisture from the consumer’s saliva causes the cells provided on the surface of the tipping paper to release the encapsulated flavorant. The first region includes a plurality of spaced apart elongated struts with adjacent struts being joined. The series of segments are mounted on an outer surface of the electric motor and gaps between the adjacent segments are adjusted to bring the plate members into close contact with the outer surface of the electric motor. A method for identification of suspects is also disclosed.
