<p>A machine (10,110,210,310,410) according to the present teachings includes a machine housing (12,112,312,412) and a drive mechanism (14,314,414) disposed in the machine housing and driving an output member (40,340,440). An input member (32,332,432) is associated with the machine housing for activating the drive mechanism. A working member (42,342,442) is driven by the output member. A light source is coupled to the machine housing that projects UV light onto an area proximate to the working member. According to additional features, the light source can comprise a UV light source. According to other features, the light source can collectively define a light emitting device and a filter. The filter can allow black light to pass therethrough. The light emitting device can comprise an incandescent bulb, a light emitting diode, or a fluorescent bulb according to various examples.</p> |
