Abstract
A twin headed flashlight includes a generally hollow, cylindrical body member with an interior body cavity sized to contain batteries which supply power to the flashlight. At one end of the cylindrical body, first and second flashlight head elements are mounted. The second flashlight head element is rotatably mounted to the cylindrical body such that the second flashlight head element can be rotated away or outboard from the axial centerline of the cylindrical body. In one mode of operation when the first and second flashlight head elements are juxtaposed near each other, a generally singular beam of light is emitted by the flashlight. In another operative mode when the second flashlight head is rotated outboard from the axial centerline, two divergent beams of light are emitted from the flashlight. Of course, the user can rotate the second flashlight head to a desired angular position within the maximum range of rotation (approximately 50 degrees from the axial centerline). In a specific embodiment, the first and second flashlight head elements include corresponding lenses that have respective, complementary mating edges. The mating lens edges are complementary to each other. Othe…
