摘要：
In one aspect, a lighted tip for attachment to a flexible rod comprises a tip body having proximal and distal ends, a mechanical connector at the proximal end, a lens connected to the distal end, a light source that emits light through the lens, and a holder coupled to the light source and the lens. A circuit is completed or interrupted as the holder moves in relation to the tip body, thereby switching the light source on or off. In another aspect, a lighted tip for attachment to a flexible rod comprises a lens forming a distal end of the lighted tip. The lens is cylindrical over at least some of its length, and the tip further includes a light source at least partially within the cylindrical lens portion and a mechanical connector at a proximal end if the lighted tip, for connecting the tip to the flexible rod.
